I used to play Conquer Online way back when, it was just the 4 classes, no mounts, etc. Any similar games that could be recommended? I'd rather have 2d but I'll take 3d suggestions. No mounts or pets, no excessive upgrading systems for equipment with a bazillion different types of stats, etc. Just run around kill a crapton of monsters, level up, buy new gear that can have a couple quality levels, then go kill more monsters. I guess I'm looking for a very simplistic grind fest to zone out to once in awhile.
