I would love to see one set in Manchuria during Soviet Invasion of 1945. You could play a an american trying too get some critical intel. The other one oi would love to see is something set into the Russian Civil War, i don't know how widespread automatic weapons were but at the end of WW1 they were already used. A Winter War game would be nice, you could fight the Russians in WW2 as a god guy. A shooter set into the Iran-Iraq War.
Well, there's Red Orchestra and Red Orchestra 2 which are set on the Russian front during WWII. They're both multiplayer but Steam says that there's single player so I don't know. I wouldn't mind seeing a game set during the Cuban revolution.
World War I, the Spanish Civil War, the Crimean War, the Northern Expedition, the Russian Civil War, etc.
Played both Red Orchestra and RO:2, they're great games and you can play as the Russians, not that I prefer to There is also a pretty big modding community, with one that I know of working on a Karelian Front mod, but it's slow going as the team's had some setbacks. http://karelianfront.com/
Ok. As far as SW is concerned a mando shooter would be awesome in almost any era minus the LOTF-FOTJ period.
