Another reason to celebrate divorce!
Maybe I need to play more role playing games--they are certainly really popular. The immediate nature and constrained length of the game I play works really well for me. We have Ori and the Blind Forest, which is gorgeous and I liked it, but once I finished it, I had no desire to play it again. Also, as I played through it, I got frustrated by certain points where I couldn't figure out what to do or where to go, or just couldn't master the skill I needed to get past a certain level. As a result, it wasn't nearly as strong a draw to get me to flip on the Xbox and waste an evening.
World of Tanks is essentially a first person shooter, but the "person" is a tank, and there's no gore to it (both of which, the tank and the lack of gore, appeal to me).
I've been surprised that there aren't more flight simulator games. I have a free version of Ace Combat 7, which is pretty cool, but hasn't hooked me the same way the tanks have. We also got Flying Tigers: Shadows over China. It could be a great multi-player game, but that requires a player base, which it just didn't develop.
