I tried TF2 competitive, stood in the queue for 20 minutes and never found a match.
Of course it's beta and means less people playing, but doesn't change I couldn't play it.
I been playing Enter the Gungeon and while I enjoy the music, the graphics and the idea, the ammount of bad weapons in the game means a succesful run is heavily RNG based. I'm sure there are some gaming pros out there who can't beat it with just the starting gun but the game is quickly running out of steam as I re-do the starting zones again and again.
My tip for people who do roguelike is the RNG should swing both ways, and a player would eventually get lucky and get a game winning combination which would carry him to victory.
