I guess this together with playkey could help keep the costs of gaming down even more, assuming that Re-selling a game or account would be with a cheaper price then a new game, or all the games separately.
Possible future collaboration maybe?

The gaming industry is huge, and I agree with your statement that competition improves the quality for consumers. If the tech and marketing of PlayKey is good, they will find their place
