So i bought C2 on steam, and im using it since a pretty long time.
Here are the Pros and Cons.
+Its cheaper (I got it 50% off in sumer sale)
+Time tracker (Not such a big Pro ;) )
-File association in explorer broken (Not such a big deal)
-Once Scirra, well, didnt updated the database correctly, an .exe was missing.
-You have no Forum badge :(
-No Lightning Draw Badge...
But all in all its not bad, the period with the crashes we all had, regardless of which version it was, since it was a common problem/bug.
If youre a common/hardcore Steam user like me, you should buyn0 it on steam.
