If I recall from some of the older FS posts the OP is selling these games for his friend. I recognize the games from discussions I had for a different title.
The seller and OP were both really cool to me and are very well aware some of the games are well above what the average price is for those titles. I think if someone wants this game with all the mods/upgrades they'd reach out to the OP/Owner and see if a deal can be made. They were both reasonable when I spoke to them about a year ago.
