babark: Have you played Trine? It's a game I highly recommend to everyone when the topic comes up, but I found the final boss too hard and just gave up on it and watched the ending cinematic on youtube.
The first one, yes, I played through that some years ago, but don't remember the final boss. I guess I managed to beat it eventually?
babark: Also the original Torchlight had some annoying balance problems with its final boss as well, where the build I had up to that point (fireball sorcerer equivalent?) was absolutely useless, and there was nothing to do.
I never got that far in the first Torchlight, I only played through the second one. With the first one I got bored after some time, since there were so many dungeon levels all looking similar to each other, and the randomly generated quests didn't help to hold my interest either.
