Probably my most favourite game when I was a child had to be Sonic 3 & Knuckles. Played the living **** out of that when I was a youngin'. Apart from that, it would probably be Roller Coaster Tycoon, which I happened to download yesterday and have been happily playing. Ahh, nostalgia...
Let's see... Sonic (can't remember which one) on Sega Megadrive Spyro (can't remember which one, I believe this was also on the Megadrive, but this is going back almost ten years) Pokemon Ruby/Sapphire on GBA LEGO Star Wars on PS2 Destroy All Humans on PS2 NFS Most Wanted on PS2 Well, those were my favourite games, in rough chronological order, from the ages of about 6-12. Of all of them, my fondest memories are of the last three.
SuperSmashBros Melee, Alien Hominid, Pokemon (all of them), Metroid Prime (all of them), and Destroy all humans.
THIS^^^^^^^^ All day. I actually just got a SNES emulator. And have been playing Super Metroid. My favorite game of all time. Also 007 Goldeneye for the N64. Or Final Fantasy 7.
This was always in competition with Banjo Kaooie, Banjo Tooie, Ocarina of Time and Majora's Mask for me. Still have them all, still love them all. Even if it did take like 10 years to finally beat DK. Damn Nintendo Coin.
