[quote name='Jerykk']If you regularly buy stuff from GMG, I don't see how credit is any worse than coupons.[/QUOTE]
(A) My initial purchase gets no discount since my "discount" is in the form of money back on a future purchase.
(B) 20% is 20% is 20%. But a purchase of
Sleeping Dogs right now gets me $6 credit. Towards a $50 game as my next purchase, that's a 12% discount. Towards a $15 game, that's a 40% discount. If I'm buying a newer game, it's far, far worse than a 20% voucher.
(C) I never know when my next purchase with GMG will be. Maybe the next game I want will be on sale for a better price at Amazon, GGG, Steam, GamersGate, etc. So now, instead of having saved the money and having it in my bank account for use anywhere, it's locked in a GMG credit.
(D) Obviously "locked in credit" is what they want so I can have the false illusion next time of "This game only cost me $44 instead of $50!" when the reality is that I paid part of that upfront with my last game purchase. If GMG was offering credit values exceeding the sale prices of other vendors, maybe it'd be worth considering. As is, I'd be a fool to tie up my money in GMG credit rather than having it free to spend at the other half-dozen guys.
(E) Don't even get me started about the ridiculous "cash back sometime later in the week" option.
