Pretty solid argument. Yeah, I notice recently I have been possessing both less interest in gaming and time to spend on it. Between getting straight A's in College and finding jobs in the summer, I have had less amounts of time to kill than I did say during my high school years, or earlier. This doesn't necessarily mean I have had absolutely no time to kill at all, as the lack of a job during semesters has pretty much kept my weekends open, most of which I either spend hanging out with friends or gaming (or both). So I can definitely see where the OP is coming from.
However, I will still argue that the current state of gaming isn't a very good one. True, games have the potential to be infinitely superior to anything we've seen in previous eras, but that doesn't mean they necessarily will be. Take for instance all of the CoD/Gears of War clones we've seen as of recent. Yeah, developers could create a concept of their own for a game, or take a previous concept and improve on it, but instead they'd rather just copy and paste a system someone else has used in attempt to milk the "realistic shooter" cash-cow.
Also, even though I still play games every now and then, rarely do I play any of the "big hits" found on current gen consoles. This is mostly because I find most big games like Mass Effect, Dragon Age, Oblivion, Fallout 3, etc. to be fairly dull and unsatisfying. Maybe I can't get into these types of games because I'm stuck in some sort of nostalgic mindset and will only accept games that mimic the old ways, as my snes games probably get more attention than my 360 ones. Maybe my taste just differs from most others, and all I need is a new concept in gaming that will appeal to me personally (like when I discovered guitar hero on the PS2). Or maybe I am just getting older like the OP claims. Regardless of the reason, I still have yet to find a current gen game that even comes close to blowing me away.
