if i see 5-stars as a win/highscore then powerups are an easy/fast way to get that. and on pretty much any song the only way to get gold would be with powerups
if i see beating RE3 within for example 2 hours as a win/highscore, then the rocketlauncher makes that a lot easier. i can probably only beat it in, let's say 1 hour if i actually have the rocket launcher.
also, i noticed on your xbox profile you played a couple of racing games.
how does it feel to play a track (song) with bad cars (bad/no powerups) over and over, just so you can later play that same track (song) with the good car (better/more powerups) you just purchased from your winnings?
i've never heard anyone complain about it there
