You don't think I have?If gamers stopped pre-ordering games before they were reviewed and known to to good, a lot less poorly-optimised games would be released. You may want to discuss this with the person in your mirror.
I never bought Sackboy until it got patched and fixed. I only bought Callisto because I wanted to support this team and their new IP... and knew full well that I could refund it.
I was almost set to refund it.. but then they patched it and promised more optimization in the future.. so I kept it.
There's a lot of games I haven't bought until they've been fixed.. or at all... and I won't support them until they do, it's that simple.
