Here's some examples of the choices I've given in the poll:
Concept art / Dev pitches - Done quite often in Kickstarter projects. Understandable for games which have barely started development. (Example)
Screenshots / Previews - This is when a journalist (or whatever you want to call them) tells you about their experience with playing the game. Entirely text based and includes screenshots. Or you may just get hyped by the screenshots. (Example)
CGI Trailer - Common practice in showing off your game at E3 without actually showing your game at E3. Pretty though. (Example)
Unfinished game footage - Includes all trailers that have the "pre-alpha footage" or "in-engine footage" text at the bottom of a trailer. Also includes when games like Call of Duty: Advanced Warfare, Destiny and Star Wars: Battlefront EA were showcased where the devs talk while you see them working on the game. (Example)
Conference demo / "Vertical slice" - Ubisoft is the king at this. Last year they showed Rainbow Six: Seige, The Division and Assassin's Creed: Unity this way. This is when someone (or people) you don't see are playing the game while you watch. Heavily scripted most of the time. (Example)
Gameplay trailer - Just a simple trailer which shows footage of the game that looks exactly like what we see when we play it for real. Difference from previous choice is that it's edited in the way of a trailer (can include graphics, spliced with other things and accompanied by music), unlike 15 minutes of uncut gameplay. (Example)
Playable demo or build - A demo for a game coming in a week or so, or is already available is released to be downloaded by the public. Includes when made available on a show floor as well. Done sometimes by Kickstarter projects where they give a playable build for potential backers to play.
Just release the damn game - Basically choose this if you don't or choose not to get hyped by any unreleased game unless it's going to be made by a trusted developer or it's a sequel/reboot of an existing game franchise. Or you're just going to reserve all judgements until the reviews popup or word of mouth gets around.
So! That's the choices I've given, I hope I explained them well.
