Do the games work as well on Instant Gaming as they do on official sites?

I would like to buy the Stars Wars battlefront 2 game for the xbox from Instant Gaming because it is cheaper there, my question, does the game work just as well when you buy it on the main pages?

Have never bought anything there but many friends are really convinced of the site haha

So I buy there very often. It has no difference from the main page game because it is the main page game. You will receive a droppings which you redeem on the main page to get the game. Instant Gaming sells codes for portals like Steam and Origin

Yes, it works the same way, but mostly cheaper.

Usually yes, but it can be the English version, then you have to change the language in the settings.
