The EU definitely sounds like what you're looking for, except you'd probably want to learn a 2nd language for social reasons (
many companies use English internally, instead of their native tongue), and population density might be higher than you're used to.
I can only comment on living in Australia:
*
Politics - similar to the US, but on a much smaller scale and less extreme. To us, US presidential campaigns look like rock concert tours. Still quite conservative like the US. Still have two parties: far-right/conservative/"Republican"=="Liberal"
vs centre-right/social/"Democrat"=="Labor".
*
Education - Can't be hard to beat the US education system, right?
Public schools are decent and competitive with private schools. University is deregulated and not free, but you can get an interest-free loan from the government to cover your tuition costs (
which is paid directly to the school, and you pay back via extra tax -- no work, no repayments).
*
Living - A corporate CS graduate could expect ~$50k (-17% tax). Someone with experience could fetch ~$100k p/a (-24% tax).
The further you're willing to commute, the more space you can get (
and the cheaper your rent will become, e.g. outer-suburbs house/yard for <$1k/mo vs inner-city apartment for $2k/mo).
Crime-wise, again, can't be hard to beat the US, right?
There's sure to be less guns, gangs, drugs and unemployment here on average.
*
Opportunity - video-games wise, the industry here has shrunk by about half over the past 5 years, so it's not great to be looking for games jobs, but there's the usual Microsoft/Google/Oracle-type offices, and corporate finance/etc type places.
*
English - we're as mono-language as the states, no need to speak foreign here
