Dungeon Defenders was one of the first games I purchased on Steam, and wow, what a banger it once was.

The game with almost infinite grinding potential, endless of hours well spent. A tower defense where you're forced to team up with people to succeed if you want to get the best gear. A really smart way to encourage you playing with strangers. Even if these strangers are weaker than you, they still help out by being able to upgrade your gear for you.

Trendy, or Chromatic Games as they're called now really struct lightning in a bottle. We played this game for years, and since it was such a cheap game, it was incredibly easy to make friends join you. Despite the unbalanced mess it was behind the scenes, it was a good time.
If you weren't grinding away for loot, you were probably going through the player shops, hoping to find some good armor or weapons for you to use.

As with most games, this game eventually stopped getting dev support, and the community slowly dwindled away. Though it has seen somewhat of a resurgence in the past few years, we all hope that something similar can be created in the future, with current technology.

Unfortunately Chromatic has turned out to be the scum of the earth. They create multiple DD clones, sell the game based on hype, overpromise and underdeliver every time. Some games like Dungeon Defenders Going Rogue I'd argue is a straight up scam. Others, like Dungeon Defenders Awakened had promise, but they always end up ruining the experience with a patch (such as deleting all your items, or removing things from the game so it'll run better on switch).

If you want to play a DD game, stick with the original.

This game still holds up great, although reliable information on it that isn't outdated can be hard to find these days.
Replayed this a couple of years ago and it was just as amazing as I remembered it. With one caveat.

After the Quest for the Lost Eternia Shards DLC (the only one that is really worth buying, aside from Summoner and Series-EV), the quality of the content that followed (both by the OG devs and the community dev team that took over) dropped sharply due to compounding balancing issues. I suggest playing up to and including that DLC, on Nightmare if you wish, but no further, if you want to remember the game on a high note.

The last part of the DLC introduces an overpowered enemy type that ordinary defenses simply cannot fight - but of course, the minions from the paid Summoner character can. The Series-EV also becomes mandatory after a certain point, or rather, her buff beam does. And eventually, there is only one kind of map build that you can really play, as the majority of towers in the game become useless. Deviate, and you will die.
The community devs sadly doubled down on this with everything they added, and also made things like tower-stacking-exploits or the use of virtual controllers (to get more loot, map rewards and to misuse them as dummys for tower-buffing-pets) all but mandatory. Which is a shame because some of those later maps would be interesting battlegrounds.

Jugué tanto a la demo de pequeño que cuando me lo compré iba overleaveado que flipas para el resto del juego.

No lo recuerdo con claridad, pero por lo que recuerdo era un "Tower Defender" en el que además de poner estructuras podías usar tu personaje para pegarle a los enemigos.

El control creo que en su momento no lo sentía clunky, pero haciendo memoria puede que si lo fuera, aún así sin tenerlo a mano tampoco es que pueda decirlo con seguridad, lo que si recuerdo es que el combate era bastante simple, pero tampoco me suenan muchos tower defense en el que además haya combate más activó que poner estructuras.

El diseño de personajes estaba gracioso, main caballero en calzoncillos

A very fun game if you like tower-defence games and want to have that crossed with RPG elements and a multiplayer aspect. They scale the levels up with the more people there are and the higher levels too. Each different character has different types of things used to slow down and kill enemies such as the mage can set up towers that cause damage, the warrior also sets up damaging traps, the rogue sets up mines and the monk creates auras which can reduce the enemies strength and defence when they walk through the auras, even their speed. Everyone I've played with has been very nice with a great community.
