Doom 2 is my most favourite game, being Doom Eternal my second most favourite one. I’ve never played Doom 3, I’ve barely touched Doom 2016, and Doom is meh without the super shotgun or the pain elementals.
Gzdoom is the source port I use to play Doom games. It has lots of configurations, you can use tons of mods, and freelook & no autoaim are a delight.
By the way, I upload regularly Doom 2 videos on my HardLimit (Peertube) channel.
