If you ever played Ogame and wished there was a mobile version, I'm happy to say I found Galaxy Reborn, Second Empire to be a clone of Ogame. There are 2 universes and uni 2 is 6/6/6 speeds and fantastic!! Jump on, sign up for universe 2 and hit me up, Alexander. I run The Alliance corporation. Mention this post and I'll send you a massive res boost so you can skip the tedious start process.
Warning: this is a sandbox mmorpg and no second chances. I highly recommend you read the ingame guide and follow the starting process as described. Get ready for constant dead phone battery!!
