Capcom vs SNK 2 was my favorite of all time... mainly because the fighters were so unique yet easily to handle... unlike most fighters: Where you either have to be a MASTER OF CONTROLS or a CRAZY BUTTON MASHER.
I would love coloring the characters and giving them different names... Ah~ it's been so long since I've played it (my bro sold our only copy)... I'm still looking to purchase it once again.
