I dunno. I don't play many fighting games xDWell, what fighting game that carries over old stages/maps 1:1 makes any changes to them?...
Anyway, the value here depends on multiple factors:
1) How many hours you put into XV1
2) If you bought all the DLC for XV1
3) If you care a lot about the gameplay changes they've made (which are significant)
4) How much you liked XV1
5) Whether or not playing a lot of the old PQs (some slightly remixed to include new characters and/or fixed up to be less annoying to play) will make you bored (there's 100 total PQs with at least half being old and half being new)
6) Whether or not the bullshit AI in the first game being completely gone in this one is something that matters to you (as in they no longer have super armor, infinite Ki, or infinite Stamina; you can see their Ki and Stamina now)
If any of the above are sore spots for you (or don't care for them), then the game probably isn't worth $60 to you and you should wait for a price drop to around $40. Otherwise, the game is a mix of old content and new content to, essentially, have more content than XV1. Along with great quality of life improvements to the gameplay.
Anyway. Thanks for the response! I loved the first game and played all the DLC and stuff. But yeah, I think you're right in that I should wait for a sale. I think I'll be looking at it the wrong way if I pay full price right now.
