Where and how to buy this wonderful game for the rf region

Companions, interested in the current issue at the moment, what are the options for buying the game in steam with the established RF location?
I found one of the instructions here on the Internet https://www.playground.ru/misc/guide/kak_kupit_igry_nedostupnye_v_steam_bez_posrednikov_smeny_regiona_i_na_svoj_akkaunt-1607636
But there is no guarantee for gta iv, maybe who went to similar steps, share your experiences
p.s. pirate please do not offer ????????
