In my case? Neither.
I am not really angry at all, I find it more comical about Braindrop's antics and obvious poor excuses. I get upset for other people who like the game more than I do, and I do not like when people lack integrity. I liked WVM a LOT better in the beginning, TBH I think the game has lost a lot of what kept me playing it and the ridiculous choices and delays have worn on me. I will play it through, but no longer as much into it as I once was. The latest updates have really not impressed me. Black boxes, diffuse story, redone characters that look inferior to the old. But I still try it, just I won't bother updating it until I get to the newest parts in playthrough 2 for me.
I always hope for the best, but expect the worst, especially with a developer who constantly feeds excuses to fans of the game. If he says a new update is coming out, I am sure not rushing here to see if it arrived. Historically, doing that is kind of useless.
For the "getting off on being angry and disappointed"? Another nope. TBH I like a lot of the members in this thread, I like the mods, and I like this forum. While I am actually replaying through WVM, I dislike it more and more as it goes by. I am still a fan, and am currently slowly playing through it, but the fire has burned out and I am not rushing to grab the latest updates (unlike some of the other AVN games I play and really like.)
