Julian Gollop : Unfortunately the backer tiers are not available from within the GOG build at the moment. We may be able to do something about this, but we will need to set up an independent transaction system. Steam has transactions built in.


I got this reaction twice but I don't think GOG support this . Probably we can't see them .

Also this game only 32-bit on GOG.com . But Steam version have both versions . So we got an inferior copy of the game .

Forgive my ignorance but, as a player, what difference does 32-bit vs 64-bit make?
My (admitedly limited) understanding was that a 64-bit executable would only benefit memory-intensive applications. Chaos Reborn clocks in at around 1GB (@1080p, pretty, if that makes a difference).

if it's pointless why they provide 64-bit version for Steam ? :S

For the sake of completeness, and because it likely doesn't require much more work to do so.

Actually it doesn't change anything in practice since the 32-on-64 Windows-on-Windows subsystem is present on every 64-bit Windows system, and works much better than in the old times of WinXP 64, but in the future, maybe 32-bit support will be removed (which would be bad but MS is certainly capable of this).
