Star Wars: Dark Forces and Dark Forces II: Jedi Knight. Had them in the 90's, bought them recently on Steam.
Commander Keen, see above.
Half Life series, see above.
Psychonauts, see above (except it came out in '05).
Cave Story+, downloaded some years ago, bought for the 3DS, bought on Steam.
TERA super deluxe edition. Pre-ordered, but it was taking almost two months to get up to me in Alaska, so I just bought a standard edition locally and upgraded when my deluxe finally found its way to me.
I'm strange like that. If I really like a product and believe it's worth my money, I will have no problem paying for it multiple times.
