I look for a compelling storyline that gets me wanting to progress or sometimes I buy a a game based on the prequel for example I played the first Assassin’s Creed a few years ago and I ended up buying all of the sequels after because they always ended on a cliffhanger that made me want to progress and find out more.
Another reason why I buy games may be because of the brand/name of the game for example I buy Call Of Duty Games because of the producers and the series, because they set the bar so high in all previous games I tend to expect a high level of quality.
