I found a game that sounded good on paper, but I wasn't sure, so I got the demo that was available on Steam, played it for a few hours, decided it was worth the £10 to buy it, unfortunately I didn't pay attention to when the "deal" ended for the game, so by the time I finished making my mind up it was £20, but I liked it so I brought it, and then after some much more involved testing I have decided that Infact I dont like it much
. But anyway, the Demo got me to buy the game (for twice the price too), even though I was not a fan of that company/that type of game/or any pre-quels.
