Some days, all of them except a few. Most days, none of them except a couple standouts like FF13-3, Yakuza 0, and Witcher 3. Only played 13-3 for a couple hours and Yak0 and W3 more because I played dozens of hours more than I should have hoping those games would click with me and I would get what everyone else loved about them.
The last year I spent playing EverQuest, I regret that. I hated the game by that point and was a complete dick to some people because I was not balancing RL frustrations (Work and pregnant wife) properly and took it out some people who deserved much better than I gave them.
For the most part, regret is a waste of time and energy. Acknowledge why something is regrettable, learn from it, adjust and/or make amends, and/or move on. Not saying I walk that path well but I am trying.
