Two of my favourite game franchises are Civilization and The Elder Scrolls. I played them since the first game, and I still play them. The original Civ and Daggerfall are always with me on a USB stick, in case I feel like playing them, even when the computer doesn't have them installed.

The last games from the franchises I played were Civ IV and Oblivion. The next games required a download, and to this day I refuse to pay for a digital copy only. I have a huge backlog of older games on discs, so I don't mind that my recent game purchases are largely limited to collector editions on Kickstarter.
