DISCLAIMER: I AM EU (ES)
These are the restrictions listed on the Humble website:

Resident Evil 6
RU + CIS (Exclusive Countries): AM, AZ, BY, GE, KZ, KG, MD, RU, TJ, TM, UZ, UA, LV, LT, EE, AT, BE, BG, CY, CZ, DK, GB, EE, FI, FR, DE, GS, GR, HU, IS, IE, IM, IT, JE, LV, LI, LT, LU, MT, NL, NO, PL, PT, RO, SK, SI, ES, SE
Germany (Exclusive Country): DE
RoW (BLOCKED Countries): AM, AZ, BY, GE, KZ, KG, MD, RU, TJ, TM, UZ, UA, LV, LT, EE, AT, BE, BG, CY, CZ, DK, GB, EE, FI, FR, DE, GS, GR, HU, IS, IE, IM, IT, JE, LV, LI, LT, LU, MT, NL, NO, PL, PT, RO, SK, SI, ES, SE, DE

So from what I understand, I am in the third zone listed, but a lot of people are reporting activating from whatever country they are in
I can't restrict to ROW in the giveaway, so pls take notice if you enter and you are not EU based it may not work

This game is weird: some people love it, some others hate it. I personally find it too cinematic, so the new RE7 (although not being faithful to the original series) feels a lot better to me than this one

What do you think?
cheers and good luck
