I've been pretty close to buying a digital copy this weekend. I'm a little concerned about how long there will be a viable online community for it though.
I was skeptical at first, so bought it from a store that allows 1 week returns. I didn't even play the demo (heck, I hadn't even heard of Onrush until this week).
It's the most fun game I've played this year. Right now I'm absolutely exhausted from a day of physical labour but I'm wide awake playing it online. Matchmaking on Xbox is incredibly quick, literally a few seconds.
I really enjoy racers, especially arcade ones (Forza Horizon 3 was my favourite), but always burn out on them because of the repetitive nature. This is where Onrush shines. It's not about getting to the finish line, it's instead objective based.
It's like they combined the best features of 90's arcade racers, burnout, NFS, Forza Horizon, and Overwatch (team based but accessibility for casuals).
I posted in the Onrush OT that I'm baffled it's not getting more conversation. If there's DLC one day, this will be my first xbox game I buy DLC/season pass for.
