70€ per game is nothing but a steal in white glowes. I'll say it once again, that the only two games in existance that could justify 60$ instead of 50 were MW2 and GTA5, and yet since then the games are shorter and shorter, with less and less content, more and more buggy, while the price is going higher and higher.
There's nothing healthy about such state of gaming, it's actually sad, the constant price increase while content decrease is no different than lootboxes not so long ago, whete the publishers kept pushing and pushing them, to see how car they can really go, up to a point where EU commision had to step in and ban them altogether.
The market will as always verify, people will vote with their wallets, but looking at the broader picture and all the complaints already, just a mere half a year into the gen, it's safe to say this move will bite many publishers/devs very hard everywhere outside of the US, which is the only place where those 70$ are indeed 70$.
