⚠️ Region lock ⚠️
AC: Origins has Ubisoft's region locks.
They're pretty blurry and mixed, so I am not sure what to list here. But for example, we have roughly the following regions:

NA: US territories including Puerto Rico and American Samoa as well as Canada
South America
CIS
SEA (+ Europe? + Africa? + Middle-east countries?)
From EU it shows the following list: AG, AI, AM, AN, AR, AS, AW, AZ, BB, BD, BL, BM, BN, BO, BQ, BR, BS, BT, BU, BY, BZ, CA, CL, CN, CO, CR, CU, CW, DM, DO, EC, FK, GD, GE, GS, GT, GY, HK, HN, HT, ID, IN, IR, JM, KG, KH, KN, KP, KY, KZ, LA, LC, MD, MM, MN, MO, MS, MX, MY, NI, NP, PA, PE, PH, PR, PY, RU, SG, SR, SS, SV, SX, SY, TC, TH, TJ, TM, TT, TW, UA, US, UY, UZ, VC, VE, VG, VI, VN, XK
From SEA it shows the following list: BD BN BT HK ID IN KH LA MN MO MY NP PH SG TH TW VN (does not include EMEA countries)
