A good shoot 'em up. The main game and extra content can be finished in around 4 hours.
Read the manual for a proper introduction to the story. In the actual game, a few lines before each mission won't tell you much.
The gameplay never really drastically changes, but I found it enjoyable.
In each mission, you have to kill a certain percentage of hostiles, then when done, press F1 to advance to the next level.
Enemies being bullet sponges can make it feel like a drag at times.
The game lacks an auto-save, so save at the beginning of each new mission.
Graphics are nothing special but for fans of older games can have their charm.
The game, however, is not without controversy and I would recommend reading about it and then decided if you want to play it or not.

Despite its half-baked nature, this game is still pretty expansive and can be incredibly fun when played with friends.

Pretty good art style, graphics and overall visuals.
The lack of weapons, enemy variety and the last third of the game being pretty mediocre in comparison to what came before it hurts it quite a bit though.
Despite that, I would still recommend at least giving it a watch.

This game isn't bad, but it's a big downgrade from the first game.
The lack of a weapon wheel and only being able to carry a max of 2 weapons at once removes a lot of the fun and makes certain encounters way more difficult than they should be.
The lack of campaign co-op is quite unfortunate.
The final boss is also quite disappointing and underwhelming (possible lore reasons don't excuse a bad boss)
On the positive side, the narrative builds towards something pretty interesting (even if you might have mixed feelings on the ending) and the graphics are better than the first game.

I found this game scary when it first came out, but now, it's pretty mediocre.

While choosing a unique weapon for each stage adds a little bit of variety, the game just gets really boring around the halfway point.
There's nothing wrong with it on a technical level, but it's painfully average in pretty much every regard.

Pretty much everything in this game - the gameplay, visuals, music, level and enemy design is mediocre.
Even as a kid I remember I rushed through a lot of stages just to get to the Megazord battles, which were fun.
At least you can play as 15 years worth of rangers.

Each level is mostly self-enclosed and nothing except special powers (tarot cards, which are unlocked by completing objectives during each level) are transferred.
The game is inspired by Doom, Serious Sam and Quake.
Each level (except the final stage levels) is divided into multiple subsections. An area ''closes'' each time you walk into a red circle, a lot of enemies appear and spawn, you defeat them and then advance to the next part. The levels get longer the farther you get into the game.
The boss stages are pretty cool and probably the best part of the game.
The lack of enemy and weapon variety can make the game boring around the halfway point, which is what happened in my case.
The metal tracks were enjoyable, but a bit on the generic side.
Has its good parts, but could've been much better.

An amazing soundtrack, atmosphere and gameplay make this a must-play, especially if you're a fan of older shooters. The base game and expansion can take around 20 hours to beat.
The AI felt good to play against, though enemies being bullet sponges and not that many on the screen at the same time (which was common for shooters at the time) can be a little annoying.
Graphics are dated, but have their charm.
Slightly after the halfway point of the game, new weapons and enemy types stopped being introduced. While the level variety was still there, that made the game slightly feel like a drag.

The expansion included in this pack- Return to Na Pali adds a new single-player campaign, which is a direct continuation of the first one. Adding a few new weapons and enemies freshens things up, while it only being half the length of the original makes it not drag as much.

2003

A poorly implemented save function and checkpoint system can ruin some of the enjoyment people who play for the first time may have.
The level design is pretty linear.
There are some technical issues and bugs but most of those can be fixed with unofficial patches.
Gameplay is fun and has variety. A lot of levels require trial and error to beat. The last few levels can be on the more grueling side.
The Graphics and story can be described as a comic book version of John Wick and James Bond.
An overall solid game with some unfortunate issues.

A fun game with an amazing soundtrack and a battle system, which you'll either find pretty weird or enjoy quite a bit.
The first game is the weirder of the two, having you reach max level before the final dungeon, which btw takes around half the game length.
The second game introduces magic, adding a cool new layer of gameplay. The leveling system is also readjusted.
Unfortunately the game doesn't give you a very good idea of where to go and what to do a lot of the time, making you kinda roam around until you figure it out.

An interesting form of the regular card game, made in a time where the game rules weren't completely set in stone. Fun for speed running and also has a pretty good soundtrack
Despite that, it has its flaws.
Having a guide to know which cards to grind from whom is a must. You'll get stuck or waste a lot of time if you don't.
The final gauntlet of the game is also incredibly difficult and you'll find yourself either resetting plenty of times or having just enough luck to see it through.

I consider this the best of the power of chaos games.
While the lack of game modes is still there, Joey uses a variety of decks and while some of them can be pretty annoying to play against, add some replay value.
You could also import your cards from the previous 2 games and experiment with plenty of stuff.
Joey's personality may be a bit too goofy for people's tastes, especially compared to Kaiba and Yugi, but I didn't mind it.

Kaiba may not change his deck too often, but it's more fun to play against him and the card pool is better in comparison to the first game.
While I enjoy the futuristic esthetic and Kaiba's arrogant personality, which makes him a fun person to beat, it can't compensate for the lack of other game modes. While I didn't care for that as a kid, it gets pretty boring pretty quick now.

Being the first Power of Chaos game, the card pool is pretty limited and the style of gameplay, with a severe lack of effect monsters and some pretty overpowered spells is just not that fun.
Not to mention that Yugi pretty much never changes his deck and then you could lose to exodia, and this just isn't as good as the other 2 games in the series.
