Nice lists dudes those are good games there to.
That's a tough one haha okay no Turok that will make it very hard. But I enjoy this I am an fps freak I think but taking away Turok is like stripping me xD
Duke Nukem 3d/64- Genuinely the same game except I think the DN64 version the Duke is more of a hero saving the babes while kicking ass I kinda like that.
Blood- I live agaiiiin. Seriously this game is really great if only the source port would release it would be even better. But I still enjoy playing it however.
Shadow Warrior classic- This is like Duke 3D's build brother but its not just an imitation. Everything is a bit different the art the style and there is nice additions to the build engine for it. Being a different type of character is also fun.
Doom 64 - I think this game was great just like the classics with major touch ups this game has the Doom atmosphere that I want to see its even better on pc though with Doom 64 ex
Goldeneye 007- not much needed to be said for this one its was a trend setter.
Avp Classic 2000 -fast paced fps classic action with aliens and predators perfection.
Prey - Turok's long lost cousin heheh bad ass game.
Serious Sam 2 - Not the biggest Sam fan but the games pretty much kick ass and this is my favorite one. Even know all of the titles offer some fun
Painkiller H&D Awesome dark gothic type of fps nothing but action.
Doom 2016 The sp is amazing we need a Turok and Duke game like this now.
