Theme Hospital | GOG | £1.49 ($2.39, RRP: $5.99)
Theme Hospital is one of *those* games. You know, the ones that always get mentioned after a few drinks and a chat about the good old days; games that stand the test of time and are properly hilarious to boot. At £1.49, it's well worth checking out even after all these years, especially since GOG.com assure Windows 7 and 8 compatibility. DOSbox, but better than playing Russian Roulette.
