Redeem games in Russia and play in Europe?

I think that you won't be able to play RU locked games in europe since you can play them just in certain countries... and EU ones are not part of it.

as far as i know if you are originaly from russia and you go to other country your account will keep with rubles but store will have a different currency and you wont be able to buy anything (not even with ?cc=ru) and steam support wont help as well but with teamviewer or vpn/proxy it will work BUT steam is a bitch and they will eventually ban you if you do it often
edit: i forgot but as antipativome said some region locks wont let you even play outside russia :/

Yup. You live in Europe now, you have to pay European prices.

If you get caught by Valve, they can and will kick you to the curb.

As for playing games out of region, sometimes it's fine, but sometimes it isn't. I had a Japanese version of the Hitman Sniper Challenge, that played fine while I lived in Japan, and then stopped working when I moved to USA. But years later it started working again. Why? Nobody knows.

If your steam account was created in Europe, you can only purchase games in Europe, activating RU games using Teamviewer or VPN will be a violation of Steam TOS; whether or not Valve is going to hunt you down for that is another story. Accounts can be tied only to a single region at a time, changing that setting requires contacting Support and proving that you moved to another country.

Are you a spy?

using teamviewer is the same as using a vpn, so yes, you are breaking the rules

No, now you live in Europe, Deal with it.

I read somewhere about dude that moved from usa to china and got screwed because he couldn't play single game from his steam library... Intellectual Property laws suck
