A Return to SoF2

Feeling a little nostalgic I decided to see if SoF2 was still a thing and stumbled upon your website and forums. I played the game A LOT back in the pre CoDMW days and was involved in a couple of clans. I suspect I still have the game loaded on an old PC which I could access with a little effort…my question is, would this approach still work? Or would I need to re-buy the game (I seem to recall I was fully patched and had a huge library of custom maps). Looking at your forum it appears there are still a few people playing and you do host a few competitive games, so I’m hoping it might be a way back into it for old times sake…although I’m well aware my glory days are long in the past!! My son (18 and a very good Rainbow 6 Siege player) has also said he’d be interested in loading and playing the game for a bit of fun after hearing some of my anecdotes from years past. Anyway, grateful for any help/guidance given…Happy New Year, Sandy x
