Fishing, traveling, etc will be good "vacation" get aways when I retire. However, as technology continues to advance, the portability of game systems will advance and I can envision there will be virtually no where you go that will not have the ability to attain global access to connect with all your "buds" for some multiplayer carnage.
Besides, I have friends that I have met through gaming online over the past several years that I look forward to having some time to meet up with in person to game with and have annual outtings at E3.
I see MAG at the forefront of this Massive Online Shooter "revolution." Whether it is fully successful or not with their ability to maintain some control and balance over global lag. I believe they will most definitely find that console gaming community will continue to support this expanded game play.
But no matter what, my plan is to continue to expand in gaming and share that excitement and enthusiasm that I have for it.
