First off, great game. Easy to pick up, hard to be great at, makes for a good game in my eyes. Now i'll post some day one thoughts on the game. As
Lady Bug said, character customization is fantastic in this game, not very important to a fighting game such as this but still good to have. Mega Gengar is strong as all fucking hell and basically a round win if you get it. Sceptile has fantastic zoning capabilities from the few times i've played it online, very hard to play against imo. Power really does mean power in this game, Machamp, Garchomp, Chandy are all super strong. Machamp in particular seems like it will be a very good character from the limited times i've seen it, 2 hits and half your health is gone. Suicune from watching
videos seems insane in the correct hands (watch the video on mute shofu yells a lot for some reason). Not a great big fan of speed characters so far but the game has only been out for a day. I played online with
Gangnam Style earlier tonight, very smooth, no lag. Overall this game is super enjoyable and much better than I expected (nintendo has a tendency to fuck things up), if you use this post, or this thread for that matter to influence your decision purchase of this game I would say it's worth the money and you will have a very good time while playing this game.
