Played through the Quake II remaster on medium difficulty. It's now a much better game than it originally was on PC with its subtle gameplay tweaks that go a long way. I never used to be a fan of this game and now I am.
It includes the N64 version, or rather a rebuild of it using Quake II's engine. (More specifically, Nightdive's KEX Engine remaster of the Quake II engine.) The N64 original used a modified version of the Quake engine used for Quake 64, so it actually plays quite a bit different. As such, it's not the perfect recreation of Quake II 64 that I'd hoped it would be, but it's a good effort, just not something that replaces the original.
