Yes if i had the choice i choose Llyod Irving from ToS! Anyway, this isnt a personal top 20 list but most realistic list. Pacman wouldn't be anywhere near my top 20 (personal choices). But i try to be reasonable with my list! Wait intill you see my top 10 realistic characters. Espcially top 8 (i guarantee at least 5 characters will make it in from my top 8
I'd want Lloyd Irving as well. People want him so much, and he fits well. There's a lot of swordsmen already, but he's got two swords and his artes, which makes him unique, the Tales of series' fighting system already resembles smash bros in terms of special moves mapped to directions, and let's face it, he's just cooler, so people would enjoy it much more. Sheena would be interesting too though (summoner ninja), and still recognizable I think. Colette too (she's got those weird ring weapons and lots of buff/debuff moves). Lloyd would probably be the best choice. Of course, they could take Cress from Phantasia, or any of the main party from that. Ya know, there should be a fighting game for the Tales of series...
But yeah, there are a lot of really obvious characters that would really shock me if they weren't in. I'm sure we're thinking of a lot of the same characters.
