Another vote for WCS. And I don't even know why I hate it, pretty sure I should like it. But for me, it's fit for the pit.
Black Knight. Pretty sure I had the nicest one in the whole country. But I didn't dig it. It was just monotonous. Which is not really "hate" I guess, it's just "not like".
Not much other hate. Most games are pretty awesome, even the ones that take crap from a lot of people.
