The first two fallout games were great and even fallout 3 and new Vegas were pretty good. I think the latter two were good because they were smaller and actually did have some interesting stuff to find and do even though they did the open world thing.

I played the m&m series a long time ago, they kind of blend together in my head with bards tale, ultima, those gold box d&d games and games like those. The puzzles in those kinds of games always made them enjoyable.
