I am a level 41 player. I quit 4 years ago when the game became so boring to play, all we do is endless upgrades. my last special event was when I got Sheila, from there I stopped. I have produced it but never upgraded. now it seems the game is fun again but all my units were so old and can't even hit a level 3 thorium base. What should I do, is it worth playing this account again or should I create new? If I would continue this account, what units should I first get and upgrade so I can catch up. Thank you..
