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.
