Two games that are bad in a lot of ways, but I've built a nostalgia raft around them since they were the only ones I had for a time when I was a kid.
Command and Conquer: Tiberian Sun: Got this after trying Red Alert on a friends computer, and I LOVED it. I still get shivers when I think about the sound of a Banshee taking off, or tunneling into the enemy base with 4 engineers and a cyborg commando. The actual gameplay is slow as hell though, and the game's generally pretty unbalanced. But oh, sweet nostalgia. Killer soundtrack too!
And Oni. Boy did I love Oni. I still hold that it has great gameplay - really tight 3D martial arts combat, haven't seen anyone match it. A lot of fun weapons too. The environments were really boring though, and a lot of the game just felt uninspired. Still, it's a game that I occasionally have to reinstall (all 500 megabytes of it
). When I read that it was designed with multiplayer arena combat and vehicles that never saw the light of day, a little part of me dies.
