“All I really need to tell you is that one of the weapons shoots shurikens and lightning. I wish I had made that up. It shoots shurikens and lightning! This gun could only be cooler if it had tits and was on fire.”
It’s a cheesy Doom-like game from the Quake 2/3 era
I actually am one of the few fans of all 3. I’m also looking into Planet Coaster made by the same people that made 3
You won’t really appreciate how good 3 is until you start messing around with the UI and really get a feel for when you’ll need to toggle on ride height flags and path height flags, etc.
Late to the thread, and you already have loads of suggestions, but Portal and Portal2 may help your partner with their spatial issues. I’ve heard that those are the games to use to introduce someone who doesn’t play videogames in general, but specifically FPS, to the media and basic controls that most of us gamers take for granted.
Also StarCraft 2 can be modded with MassRecall so you can go through the SC1 campaigns, more than just SC and Broodwars, in the SC2 engine, which makes them a bit easier and more satisfying. I think that would allow you to do co-op on the original single player campaigns.
