Oh hell yeah I’ve played almost all of both series.
Flatout 1 is alright, hasn’t aged especially well. Suffers from being completely overshadowed by its sequel in every way.
Flatout 2/Ultimate Carnage is still my favorite Bugbear game, with Wreckfest being a close but firm second.
Flatout 3 is.
Flatout 4 is honestly not terrible, but still feels like a cheap imitation of the first 2 games.
Burnout 1 also suffers from sequel shadow.
Burnout 2 is a great arcade racer that no one talks about because…
Burnout 3 is quite possibly the best arcade racer ever made. Absolute masterpiece.
Burnout Revenge is somehow just as good. Whether I prefer this or 3 depends entirely on how much I enjoy traffic checking on that day. I posted Junkie XL - Today to the music community a few days ago because I was playing Revenge recently, what a soundtrack.
Still haven’t played Dominator, should probably get around to that.
Burnout Paradise is also excellent in its own right, but I think going open world took away some of the charm that the previous games had. Tracks were so well designed in 3 and Revenge. Still love Paradise too, but 3 and Revenge are just absurdly good.
