Topic: Steam <-> non-steam
Allow Steam accounts to fill email and password on site.
And non-Steam players to not lose their logins after linking to Steam.
Pros:
Use Steam or standalone client to play.
No dancing with multiple Steam accounts.
Can launch perp and other game on separate computers (Steam not allowing that for some reason. Can login in steam from multiple PCs, lauch multiple games on one PC, but not launch games on multiple PCs...)
