So let me point out some cons and pros.
Pro-
1. Runs ten times smoother on Windows 10, the new scaling is awesome, along with no laggy ctrl esc/randomly popping up in middle is nice
2. No more login, you choose a login name before joining the server and can save it to such
Cons-
1. If you go buy it, you no longer have a chance to change CD key (all steam/beam generated)
2. Due to this CD key issue, you have 0 (I mean fkin 0) characters even when using your original login
3. Sometimes it pops an error saying you aren't on the same version of server, I had to exit and reboot the game (pretty instant but still)
So, now I have 0 characters, lost all my gold in my bank unless I reinstall the ghetto version that has worked like total sh*t on windows 10
with running a nvidea 1070.
So far that's what I've seen.
