There are several "slower-paced" action games too, as it has been pointed out, I'd say probably Flashback is one of those.
Also, Desert Strike, I can't say that this is a fast-paced game (and I love it).
Let's say that mostly I'm trying to identify valuable strategy/managing games for Amiga, where in general there are much more options for PC, obviously, I'm not taking modern games into account
