I'm not judging anyone over their choices, you should do whatever you want with your time, nor do I think about this concept of having a "social life", I enjoy being around people and having a few drinks, I don't need to justify it to myself with gay modern concepts of what is acceptable or not. I work from 9 to 5:30 and that's what I look forward to most of the time. If I'm feeling tired or just not in the mood, I'll head home, put a film on or read a book - it's all down to you really, I prefer to do those things with my free time over playing video games.
The forums have grown into something I can't really explain, I loved playing games when I was younger, and just like all of you I loved GTA. 10 years is a long time, things change, by the time San Andreas was released for the PC, I was already half assing my gaming time. At some point me and a few friends stumbled into WoW and I completely stopped playing anything else, that game was virtual crack. I played that from 2005/6 till about 2011, the game (badly) changed over the years and I lost interest in it too. I haven't found any enjoyment in games ever since... but I do like the people here and the conversation outside the GTA related forums.
