I pre-ordered Risen 2, it was one of the last games I pre-ordered. (bar KS) It was very expensive, buggy and overall disappointing. I've learnt my lesson, I now read reviews first and wait for steam sales. I recall pre-ordering Skyrim to, within one month it was on sale for 2/3rds of the price… Nope I'll wait in future. Daniel.
I practice waiting too. My view is, 'a game's not old if you never played it.' That works most of the time.
But I keep a healthy back log of games so that when new one's come out, with few exceptions, I have the patience of a saint and can wait for inevitable patches and price drops.
I did buy Skyrim on release and had to learn the lesson yet again. But I've been good since then.
