I think the Aladdin war should be like some kinda personality test on what it says about you as a gamer. If you saw my review of the other Aladdin, you'd see I prefer the SNES one.
For example, Aladdin for the Genesis' strong point is that its animation was done by professional Disney animators. The game is definitely beautiful and the movements have so much personality to them. You can even detect strong secondary motion which still wasn't very common in sprites at the time. The cutscenes also have portraits of the characters that are very expressive. The only fault for the visuals I have are that the bats are way too small, and for some reason they made parrots random enemies when Iago is a major character in the movie and even a boss in this game.
The other major difference is that Aladdin has a sword here. It doesn't amount to an awful lot in the grand scheme of things as you can still throw Apples and that's the better move 99% of the time, especially against bosses (Even Snake Jafar who has a safespot if you switch phases while he is completely off-screen) While we're talking about Al, he doesn't speed up right away, and if he goes too fast, he'll slide before stopping which is a bit frustrating. Hitboxes of platforms and enemies are also tricky, as they will either feel too accurate to the image or fairly off like certain platforms.
There are also camera issues where Al can get too far close to the right. This can be solved by turning left and then turning back right, but it came up enough for me to notice it. This was likely fixed in the Final Cut version of the latest rerelease.
The levels, as eh as they are for gameplay purposes, do lift a lot of elements from the movie, especially in the Agrabah Rooftop level where most of the things presented in the song segment show up in the game. Both games are faithful but you still love to see it so I will still mention it here.
The music pales when recreating the film's soundtrack as the Genesis soundchip just wasn't built for it, but it was good enough to get me humming the songs all over again. Prince Ali plays on level 1 while One Jump Ahead plays on Stage 3 which feels out of order. The original songs work well as they were made with the Genesis in mind, I like Escape the Cave of Wonders and Jafar's Palace myself.
The level that compiles all these problems into a package is probably the Sultan's Dungeon. It's a bunch of dark blues, precise timing platforming with wonky collisions, the goddamn bats that blend into the background so you're bound to take a hit, and the maze-like design...I'd rather not do that again. Not exclusive to the Genesis version is the unfairness of the Rug Ride while escaping the Cave of Wonders which sucks in both versions.
Some people prefer this version, that's fine, but I prefer the SNES one for how it plays. You can't go wrong with either version of Aladdin however so while I'd recommend the other one more, you can't go wrong with the Genesis either.
