So I have been playing games with friends of rebellion as a regular occurrence for years and years. As someone who has most of their games installed through steam, and I remember playing the original Sins, diplomacy, entrenchment ect as they came out I wanted to start playing them again. I realised I never owned them through steam, and then after many searches and trying to remember the name of various platforms and resetting passwords, I found my account here and realised that yes I do own all of the games, and from my purchase history, apparently I purchased all the games separately, then again as trinity, and then apparently a third time as a trinity box set.

Is there any way to activate my license I have through the account here on steam? Or is my option have a seperate install through the download, or re purchase the game again through steam to get it on my steam account?

I love the game and would love to have them all avalible through Steam as thats where I have all of my games collected.
