That's a tough question. I generally had a good idea what games I bought and what to expect.

One exception was Mob Rule, which was a bit less tedious than Constructor (which is NintendoHard at a certain point) and as such much more enjoyable to play. Didn't expect that.

The game Darklands was also much better than I remember it from a few years ago, but I put in much more effort than before and got over that early learning curve (more of a vertical cliff really).

American Conquest, Outcast and Blood

Yeah I started playing it about 2 months ago, and I really liked what I played of it. The controls take a little bit of getting used to.
Another game that I I had never heard of that I ended up enjoying was Nox. And oh yeah Independence war 2 seems awesome even though I have barely played it
