I used to have the most firey hatred for this series, you guys have no idea.
Some of the newer games are fairly clever in some ways though. They would never work good in a serious tournament, but I think they are pretty funny, at least.
And the past 5 or so games have had just an incredibly wonderful amount of content, with literally hundreds of hours of unlockables, in everything from characters to music, to art, to one of the best character creators I have ever seen, to unrelated game modes, like a free roaming RPG or a kart racing game. Who cares if they are sub par? That is a pretty cool bang for your buck!
And I have personally met Ed Boon before and he is just a very nice and generous person that really cares a lot about his fans and how games are made. Especially after seeing how some people in the industry are, I really have a lot of respect for him.
