I've been playing the hell out of a game called SSX on my XB1 lately. It's a snowboarding game on the 360 that was added to backward compatibility and EA Access sometime this year.
I've never heard of the game before, and never had any inclination to ever play any sort of Snowboarding game, but it turns out this is one of those games I've needed in my life for a long time but never realized until it had already fallen into my lap. What a fun damn game.
I think one of the things I like best about this game is that it's the closest thing to a casual kart racing experience I've got on the Xbox 1 (actually, closer to one of my favorite Wii games, Excite Truck), in that it isn't some hardcore realistic racing simulation that bores me to fucking tears. I love pulling off tricks, I love the huge variety of paths I can take down the mountains, and the music is great. At this point I don't even know if they have a modern SSX game for modern consoles, but I'm gonna have to find out when I start finishing up with this one.
The only downside to EA Access, for me, has been that I've already purchased a lot of the games they keep adding to it; so by the time something is added to the vault, I've already bought and played many of them (Titanfall, PvZ: Garden Warfare, Dead Space etc). But except for that, the service is a hell of a deal and it continues to deliver. Plus I'm hyped that it introduced me to this awesome game, since this is probably the only sports game (besides Rocket League) I seem to enjoy.
