I'm building up a new penny collection, but I'm not sure what games to buy with the money now that I have reacquired a copy of Ninja Spirit thanks to rag-time. hehe. I'm thinking either Parasol Stars (I love Bubble Bobble and need to play this. lol), Magical Chase, or Dungeon Explorer II (US version).
Parasol Stars shouldn't cost you all that many pennies. I got mine last year for like ten bucks. It's an okay game, but I prefer Rainbow Islands. I know I'm in the minority on that, though, and PS is more like Bubble Bobble. And RI is more expensive.
Dungeon Explorer II is f*cking awesome, definitely the one to get of the three you mentioned. Take the original DE and throw in a larger world, more bosses, an incredible CD soundtrack, and one of the coolest Turbo villains.
I don't like Magical Chase.
