Trophy suggestions for old school games

[Sparkster]

I admit, I've been playing some newer games lately, and not so much old school games, but I've gotten hooked on getting trophies. It got me thinking what kinds of trophies should be made for older games. Obviously finishing the game, certain levels, but there are certain tricks as well that could be made. I was wondering if people here had suggestions for trophies for older games, and some of us could try to achieve them. Of course, there's no proof if you actually achieve the suggested trophy, but it makes for a fun challenge rather than simply trying to get to the end.

I.E. Super Mario Bros 3...

- Collect 15 straight Star Cards at the end of the levels (obviously not including mini-castles, airships, and mini-games)... the fire flower cards and mushroom cards are too hard to get consistently though.
- Collect all available white huts
- Finish the game without warping

Do you have any suggestions? For other games?
