Thats a rather vague question
As you have normal TTX2 games, and you have deluxe titles,
tableflip game, its purely in japnease
But if we are talking stick and buttons game, every single one of them is either in english, or no english is required to play them, or can be forced into English via test menu / external means
and the deluxe games, your mileage my vary, and we dont even have a full list of games that truely exist, so providing any type of list of what is and isnt english is going to be nearly impossible
I mean more of x2 titles specifically. i am specifically playing around with blazeblue 2 and i can not find the english option at all. the other games i really havent messed with yet so that is what lead to this question
text. the info about the characters are all in japanese and text after the round. but the button calls and all that are and round info are in english. the original continuum shift was completely in english when in english mode is this not the case with the second game?
