My favorite games:
Nehrim: At Fate's Edge; The Elder Scrolls Series: Skyrim, Oblivion, Morrowind; GTA Series: San Andreas, V, IV; Tomb Raider Series: Rise, 2013; Half-Life: HL2, Portal 1, Portal 2, HL1; Borderlands; Euro Truck Simulator; Stardew Valley; The Witcher 1
I enjoy a good classic game once in a while. Tomb Raider 1 and 2 and Half-Life 1 were part of my most recent classic sessions, and I'm already looking forward to playing Deus Ex, Duke Nukem and Unreal 1 for the first time.
Some more games in my backlog that are waiting to be played: Metro (2033, Last Light), Borderlands (2, Pre-Sequel), Witcher 2, Tomb Raider 3-9, Fallout (1, 2, 3, NV), Baldur's Gate (1+2), Cities: Skylines, PAYDAY 2, Enderal: Shards of Order
