Yeah that's completely fair! Personally it depends on the game for me. Some games I'll use mouse and keyboard on, some I prefer the controller on. Ratchet and Clank for example I'll use the controller for. Games like Skyrim will be mouse and keyboard. Plus yeah I don't imagine the laptop helps with that aspect, unless you go external keyboard and mouse of course.
Also that is a rather tough one, and I will be basing this off the Playstation side of things due to me being actually experiencing those. I never really had the Xbox to really make much use of.
I have a lot of favorite games across the PS2 and PS3 overall, and my love for the Ratchet and Clank series primarily came from owning the PS3, since I wasn't quite aware of the series until then. I also was introduced to the Tales of series on the PS3, such as Tales of Graces and I enjoyed the games of the series.
So I think I will actually lean to Playstation 3 for this one, despite having a huge PS2 collection on hand at this point in time. I still highly regard the PS2 as they have so many great games. I just feel the latter gave me some nice new experiences I enjoyed sooner before I got to really enjoy the PS2 at a later time.
I'll throw this question out there, classic Windows UI, such as Windows 9x / Windows 2000, Windows XP UI, Windows Vista/7 UI, or modern Windows UI? Which do you actually prefer the looks of?
