G2A is a Chinese game marketplace. We have followed the company over time after reading that keys purchased were invalidated. Evidently some keys were purchased with stolen credit cards.
G2A has games for the PC and the consoles. They also trade in hardware. We have not compared prices as most of the gear is private labeled and hard to tell if it’s overpriced.
Most recently G2A has been criticised over their wallet account holders. Now after an inactive period of 180 days, they deduct €1 each month. This continues until the wallet is exhausted. Unfortunately for G2A this is illegal in many nations including Canada who requires gift cards etc to be perpetual.
