Work / Is it worth for a 27 yo game artist to move from Moscow to Katowice? [14]

Hello, guys.

I am 27, single female, work as a lead 2D artist in second biggest Russian game development company in Moscow. This means I draw in Photoshop for iPad games. I have a 3,5 years working experience in game development and 2 of them are in position of lead artist.

I have a job offer to become a lead artist in Polish company. I am still negotiating about my salary but I hope it'll be 8-10K PLN per month netto. Even 8K will be good because it's almost the same that I have at home but I've read that Poland is much cheaper (well, even life in Munich is cheaper than in Moscow).

My salary in Moscow is about 1700 euros per month now (used to be 2300 at the beginning of the year but Russian money is awfully cheap now). I don't pay rent here.

I am really interested in moving to the EU because of 1) my job 2) Running away from all that is happening now in my home country. There's only one company in Russia that is bigger and more interesting than the one where I'm working now and I don't want to work there because of reasons :)

Also I'm looking forward to work in AAA project in a couple of years and it's impossible in Russia.
My dream is Berlin but at the moment it is really very hard to find a job for a Russian person in the EU because of all that political stuff. Also there're a lot of visa issues and other great artists in EU - and that won't let me find job in Germany at the moment.

But Katowice is in EU and I find it a good start for me to move to EU. I've read that it's an ugly and cold city and it's ok for me because Moscow is ugly and cold too. And also expensive and overcrowded.

Is moving from Moscow to Katowice worth it?
