Pay to play. Sorry, but I just prefer to actually own my games, rather than rent them.
On a related note, MMO/massively online experience/similar. I'm not inherently against them, and have had some fun with DDO for a time in the past, but nor am I really interested in the benefits of the 'massively' part of the title. If I play, then I'll be playing on my own or with a few friends, and will gain very little from a MMO over an identical game played on my computer at home, which also allows me to host/join a game with friends. It won't be an inferior expeience, either, but it means that a significant part of the budget will have been spent on something I'm not interested in, not to mention that either microtransactions or the aforesaid pay to play will presumably be paying for server upkeep, so it's unlikely that the features which interest me will be significant enough to justify getting the game.
(First person) shooter. I just don't find the idea of charging round shooting people in game a remotely interesting idea.
Photorealistic graphics, or similar phrases. Again, I'm not against the concept (beyond my current machine's inability to handle high definition graphics, but I'm in the process of upgrading so that's irrelevent). It's simply that high definition (I carefully avoid the phrase 'high quality') art requires a lot of budget, which is budget which isn't going into the story, or gameplay, or anything else, of the game. I'm as likely, if not more so, to be interested in characters represented by static portraits, or even polygons (see Thomas Was Alone) as ones represented in full detail on my screen. I can let my own imagination detail them, and focus on the actual characters rather than what they look like. It's also a lot harder to introduce things which look odd in a polygon's on screen movements than a photorealistic 3d person's actions. That also applies to scenery, provided of course I can tell what I'm looking at. Skyrim was where I particularly noticed this: it looked stunning, even on my computer, but the gameplay was one corridor slasher dungeon after another, with brief interludes of the game roleplaying two sides of a conversation, and telling me that I was saying one of them. Don't get me wrong, I'm quite partial to a story told in stunning cinematics involving dragons and an unlikely hero, but...that's why I'm watching The Desolation of Smaug tomorrow. I don't need that in my computer games, I need a...game. Clue is in the name!
