Nice work man!
Though English isn’t my native language either, I did correct a few things. They were minor things like moving around the € sign (its in front of a number on other wiki pages aswell) and adding a few times ‘the’ here and there.
Since you wanted to know what you did wrong… well the only ting I could find was that you wrote ‘…Europe and the cities are procedural generated and…’ in the gameplay section. Thing is that ‘procedural’ in that sentence is an adverb so I changed it to procedurally.
Anyway good job on it 🙂
