Yoshi's Story for the N64. I remember playing this game and being disappointed that it wasn't anywhere near as much of a challenge as Yoshi's Island - you could probably beat the game in 10 minutes if you really wanted to.
I rented it back in the day and actually DID beat it in ten minutes.
The only way I could make that game challenging was by not using weapons, limiting the amount of health packs and eve hypos I could collect to three (not that that mattered, they were all over the place even on hard) and loading saved games when I died.
Even then you could still just hit people with the wrench until they froze, continue wailing on them to make them burst to pieces.
The xbox version of Doom 3. To begin with it seems quite scary, and you have to go slowly. But after a while, when you get used to it, there's so much health and ammo around it just becomes laughable.
You really do get used to the scare tactics by the end of them game. It does provide for some fun cheap thrills for quite a while though.
I played the expansion set where you get the gravity-gun-knockoff. It lets you catch projectiles and hurl them back again. It takes practice, but soon I was using next to no ammo by just killing monsters with their own weapons. Plus I wasn't ever getting hit. Doom 3: Resurrection of Evil is a long way from the "easiest game ever", but it's even easier than Doom 3.
Doom 3 was a lot of fun for me. I rented it once, beat it the second night. Maybe six or seven hours at the most. Once I got my chainsaw, the game changed completely. I decided that using it was more fun. I would go into a room, turn and jump where I assumed monsters would pop out (which I was often right in guessing where they'd be) and chainsaw the dudes brains out. I loved the art direction and overall feel of the game. I had a great time using the shotgun and chainsaw, but I felt the rest of the weapons were useless. Especially the minigun, I just never seemed to find any ammo for the damn thing. The BFG was also toned down. The cyberdemon was a joke. Overall though? I liked the game. It would be fun to use a gravity gun in the game, I guess I'll have to find a copy of the expansion pack.
If we're going to be making lists like little girls, we should at the very least automatically vote off all movie games. That would include Spider-mans movie games, but not Ultimate Spider-man. I still say Ultimate Spider-man is a joke. A fun joke, but it was painfully short. They honestly thought I'd have fun collecting things and racing the human torch around the city? Ha Ha! *points*
