Well, here's what I remember about these games.
Double Dungeons - Actually kinda fun, though not especially engrossing. There are a series of increasingly large and difficult dungeons. You start each one at level one and must get to the end to collect a letter. When you collect the letters from all the dungeons you can do the final dungeon. You wander around a first-person dungeon attacking. There's not much strategy. It's not really an RPG so much as a first-person dungeon crawler. The interface and play mechanics are VERY simple, and the music rarely changes. Some people get along with this game and some people hate it.
Ordyne - Another PCE shooter. It's OK, but there are shooters I would rather own. I don't feel like anything makes this one stand out in any real way.
Dragon Spirit - Fantastic music. Interestingly themed shooter. The only major problem is the size of your dragon, and thus your hit box. Trying not to get shot down can be a real hassle. Otherwise a pretty great game.
Space Harrier - I enjoyed this far more than I should have. The graphics are pretty good and the music is pretty kick ass. The voice samples are embarrassing.
Pac Land - A lot of folks on this board defend this game. I'm not one of them. I find it rather bland and boring, graphically, musically, and in just about every other regard as well. Sure, it's not Drop Off or Ballistix, but while there's no reason to hate it, there isn't much to love, either.
Victory Run - It's OK if you like these kinds of racing games. I don't.
I'm going to buy a couple more Turbografx games. As there's not much to choose now, I've only found games not mentioned as much when people talk about the best TG games. What are your opinions on these games?
