Bad Rats

[kongo]

skyrim, counter-strike: global offensive, rocket league, metal gear solid V, terraria and payday 2 are the "must-buy" games that come to my mind

some of my favorite games on steam are stardew valley, mgsv, risk of rain, dark souls 2 scholar of the first sin, rogue legacy, dead by daylight and mark of the ninja but other than mgsv they're not "must haves"

[Willco2]

portal 2, skyrim, half life 1, and tf2 i guess
i would say quake iii arena, quake 1, and doom but they're not worth buying on Steam rn since they require some patches and such that dont come with it
