Time zones are a pain, both to experience the differences and to live with them for gaming. I was in South America for nearly two weeks and came back to days of feeling tired constantly and out of sorts. It’s certainly affected the amount I game as I’ve been going to bed earlier than I normally would and feeling tired mid afternoon on weekends also.
Beyond this it also has affected my gaming a lot over the years. By simple weight of population there tends to be a lot more English-speaking servers in MMORPGs in the USA than in Europe. Also the games I have played or am currently playing are dominated by North American companies or publishers.
Over the years I’ve been part of a number of guilds, mostly ones dominated by players on US time zones. This means I rarely get to join the majority of group activities or scheduled meetings as they start when I’m going to bed or already asleep. The same holds for most player run events in EQ2 (so annoying) and for a lot of the broadcast play-sessions on Massively’s Twitch TV channel as well.
As a gamer, very often, it just plain sucks to be in Europe.
