Lol, you don't want the steam version - trust me. I purchased it and had endless issues. Finally got the standard version sold here - not a single issue.
Some folks have zero issues with steam, but the majority do.
Issues with steam version:
Crashes, constant crashes. Won't close. Can't open file from anywhere other than through construct program using open and select file.
Can't open multiple instances and the list goes on.
As for personal version - I understand :) and I am sure they will have some sort of christmas special xd
i'm using free version on steam... i got no issues... (not yet lol)
its more easy for me to get the steam version than standalone version (local currency is better)
