Buying PC games from overseas

This might be a dumb question but can you buy pc games from the UK and play them on a PC in the US? I'm pretty sure that it wouldn't matter for the PC, even though it's different for console games and dvd movies. (Something about regional coding? or format? idunno how that works).

Thanks.

Yes. You can buy PC games from anywhere in the world and play them on a PC anywhere too.
