My favorite game was bloodline champions. It was a fantasy Arena PvP fighting game, and had several very nice advantages:
- a game lasted about 10-15 min, so it was very cool for playing in-between other things, as a kind of break from RL work
- it required high skills, there was no auto-aiming, and you played with asdw and 4-5 hotkeys.
- it was very balanced between ~20 different characters
- I like the comics optics
Sadly it is all but abandoned, but now it's successor, "battlerite" is in town, it looks promising and I'll be playing that one as well.
I see it on Steam all the time. I have yet to play it. I may have even downloaded it.
