Europe is a diverse continent and not all countries are equal when it comes to game dev communities. I don't believe there are many AAA studios in Spain if that's what you are looking for, but indies shouldn't be too hard to find in any major city, if you are ok starting there.
There are game development conferences all over Europe, and I would suggest looking into it, and I always recommend volunteering to really connect with like minded individuals. Don't forget business cards and a portfolio.
Studios in Europe tend to have a very international staff from what I've experienced, with English as a working language, so that shouldn't be an issue (unlike east Asia.)
