Much like IntoxNitram had stated, I'm holding back on an opinion until I actually get to see some gameplay. Was hoping to see something this E3 but all we got was a trailer. I mean that's good enough when it comes to establishing the setting, which looks amazing by the way, but I've learned not to rely on cinematic trailers for my expectations, even from companies with good reputations like CD Projekt. The game certainly has the pedigree though, as The Witcher series were some of the best games of all time. This is going to be a massive success if it follows in The Witcher's footsteps.
Finding out this game is first person only was extremely annoying. Love the look of the game and love the premise but I always get headaches playing these types of games (Far Cry being the worst)
