I'm currently playing Triangle Wizard. It's a real-time roguelike (think diablo) with basic dungeon/monsters (graphical ascii'ish) and nice particle effects for spells.
It's addictive as hell, but likes a bit of processing power. It's free and can be found here:
trianglewizard.webs.comGive it a go, its like the Other DoomRL (just magic-y, not gun-y). Yes, you can circle strafe.
I just got a level 36 familiar (on the first level), 3 level 12 air elementals and 3 level 14 firesprites. As an Efreet Assassin of Ragnaros. It's burny, needly acupuncture time :)
Oh, I'm level 2 on about dungeon level 4 and would get destroyed by any of these summons if they weren't mine. Sometimes the RNG loves you, there's even a god in-game to prove it. Here's a save (zipped for space). Because, as we all know, nothing actually happened without a screenshot or some evidence.
