i've always enjoyed the mini games in the GTA games like darts, bowling (hey cousin!), tennis.
It was one of my favorite multiplayer game at the time, even more than Mario Kart ! (But less than Smash Bros...)
Also, if breaking the loading screen with sword slashes counts in DMC3 Special Edition, then that. Did a lot of that.
You are a madman.
Probing planets for mineral deposits in Mass Effect 2. By far the best part of the game (and I enjoyed the rest of the game). If they ever released a smartphone version of it, I'd become the biggest whale ever.
Me? I could play professional Pazaak at this point!
I'd put a note that this came out when I was at College doing like 13 hours a week in lectures and had a weekend job so had a lot of spare time to plough into it. Plus back then I could play games until 3am and get up full of energy the next day
Yet I still never caught the huge fish that's supposedly in there (rumoured to be in the marsh bit).
My wife, best mate and I each had a copy with 3 tvs in the living room, and we'd rotate the screens so we couldn't see what each other had.
I never played that, but by the looks of it Zelda: Twilight Princess has a similar minigame.
Monkey Target from Super Monkey Ball 1. Still the best version imo.
But I remember that landing correctly was pretty annoying 'cause you can't see exactly where you will land (can't find a better example than this).
