Doom, where do I begin? as ID software's first venture into 2.5D I have to say it is a fantastic game, even in its vanilla state. I have beaten the game in it's original and charming settings a few times myself. Now, mods is where the fun begins as they cut out the whole DOSBox setup and make things much easier for running the game. Get GZDoom here: https://zdoom.org/downloads and then set it up, then I recommend getting ZDL here: https://github.com/qbasicer/qzdl/releases/tag/v3.2.2.2-stable then you can open that up and in the settings tab set the source port as GZDoom and set the original IWAD file that you get with this download when you buy the game as the one to use. This will make launching Doom and mods much easier. Now you can get a mod like Project Brutality or Brutal Doom to really turn Doom into a better version of Doom (2016). Now note that I said a better version, aesthetically the game will still use 2D sprites. But mechanics wise the game will run and play a LOT better. Project Brutality 3.0 for example offers double jumping and mantling into the scheme of things, really turning the original Doom into a different but fun game.
Quake II is one of my all time favorite games and the Quake and Doom series are on the top of my list, I actively play both even in 2017. Quake II is one of the games that set a standard that all FPS started to follow in terms of strafing and mobility trumps tactical decisions. The multiplayer requires true skill and is still fun to play with a group of friends. The campaign tells a story although not a really in depth one and you gather most of it from reading your PDA and listening to the radio chatter throughout the game. I own the game and it's two mission packs: The Reckoning and Ground Zero already and on disc so I had no need to purchase this game a second time. I would recommend this game to anyone who likes the FPS genre and likes a fun game altogether.
