At first i'm not from Czech Republic. I'm from Poland and i want to invite you to good MMO game. E-sim is browser game in which you can be soldier, politician, bussinesman, redactor and more. It's like Erepublik but without possibilty to buy gold so everyone has equal chances. it's social game in which you play as a citizen of your country. Currently there is no Czech Republik but you can change it!
If you want to play here is the link: e-sim.org/lan.5291
It's my referrer. If you begin game from referrer you will get extra 2 gold after reaching 7 lvl.
Good luck in game!
