Wizard's Quest is a lot like Risk (on a smaller board, with some twists). I used to have a lot of fun with it. It's also an easy game to design variants or house rules for.

Merchant of Venus has been described as a railroad game set in ou-ter space. I've never played a rail game, so I wouldn't know. But MoV is well designed and can be quite fun if you like buying-and-selling games combined with dice-governed movement along a track. Sound like Monopoly? It's probably in the same genre, but in MoV, the track is long & convoluted and you get some choices as to which way to move; and there are lots of interesting twists to the buying & selling. There are also some pretty humorous design elements. It takes a while to set up but can be played by 1 player or several.

Kingmaker is an award-winning game, and I always felt I should like it--but I never really did. The main thing I dislike about it is that you move tokens around a map of England, but you have to look around at face-up cards on the table to see what each token represents in terms of army strength, etc. I found all that looking back and forth annoying. Another thing I disliked (though others love it) is the political dimension: it's not just a straightforward conquer-the-world game; there are political machinations involved.
