Just buy Rebellion. If you must have a seprate copy of Diplomacy buy Trinity when its on sale. It would run about $5 IIRC.

You are quite aggressive, he just wanted to help you. Try not to be this offensive online.

Online stores usually offer Rebellion and Trinity for sale, but just keep looking you will find a single Diplomacy for sale I think. Trinity is basically Diplomacy, only it gives the opportunity to play the original game and Entrenchment expansion too. But why would anyone play Original or Entr. if they have Diplomacy available? most modifications are upgraded to Diplomacy and Rebellion..? The option Trinity will be a mistery for me forever..

BTW you should decide what game you want, as all diplomacy features are in Rebellion, plus extra content like titans, corvettes, and developers improved almost everything in it. rebellion is stand alone, you will get full game if you buy only Rebellion, and it is patched well, you can even play online (older expansions have very few people online). Most mods are up to date for Rebellion.

Correct me if I'm wrong.

Hey, I'm just trying to save you money. For 99.9% of people there is no point in getting Diplomacy because all the content in Diplomacy is in Rebellion. Unless you want to play with friends who only have Diplomacy or there is a mod that has not been ported to Rebellion, there is little reason to buy Diplomacy if you also will get Rebellion.

If it is possible to buy just Diplomacy, it will be from Gamestop (former Impulse), but as mentioned the entire trinity package occasionally goes on sale for less than Diplomacy alone.
