Love this game. One of my favorites really. The online is full of hacked games though, so watch out.
To be fair a lot of the mods are extremely convenient. For starters you can't play this game without TQVault. I am such a loot whore I can't ever get myself to throw away anything relatively good. These games always end up being a pain to manage my loot.
Well with TQVault, I can offload all my items to an out of game location and just load up TQVault if I ever want any of it back. Now TQVault also allows you to do many less legit things, but you don't have to use it e.g. complete a relic or swap its bonus (really not THAT bad).
Also there is a mod that lets you multiply the mobs by x2 x3 or maybe more. This way you can fight three bosses instead of one. I don't remember if it spawns more majestic chests or not (probably not) but still pretty freaking cool.
If anyone wants to play with me on steam, just send me a PM. I only have a 34 Haruspex, but it's a fun game.
To the people who say what's the point of playing MP vs SP. Same as any game, why not?
