Isn't this already a thing though with resellers? Often you can pre-order games for cheaper than you can on Steam because they are discounted. That's devaluing games as well?
Resellers are a whole other issue, whether the issue is fraudulently obtained keys or reselling keys outside the geographical location of the original key or whatever mechanism involved. But yes, they do devalue games.
but i think the case is different here because a £30 game is still a £30 game. the discount is not a discount from the game itself but is "free" credit being given from Epic. If anything it devalues ALL games everywhere because i may choose to just not buy any game at all until epic do another similar deal..... but i think that is painting too wide a brush to accuse Epic of devaluing all of gaming (and if that is the case anyway then that is true of all special offers anywhere and I certainly wont shed a tear if this epic offer encouraged valve to do a similar deal their end, because that is the beauty of competition and is exactly why I want someone competing with valve).
