I'm pretty sure that most of my friends and colleagues will attest to the fact that I prefer to get my points across in a frank but considered manner.
Be that as it may, I tend to avoid buzzwords or catch phrases but recently one has caught my eye, not least because it interests me immensely.
Player Investment.

Games like Halo, Call Of Duty, World of Warcraft and many others are all supplying us with that carrot that tantalisingly teases us and keeps us ploughing hours upon hours into our games, which previously we would probably finish then leave on the shelf, trade in or flog to a mate.
A few years ago I began to play World Of Warcraft for a number of months in an effort to improve my understanding of the whole MMO genre, I was totally new to the experience and I found it very enjoyable. That said I didn't get hopelessly addicted and I was able to walk away without turning into a gibbering wreck.
The one thing that I have noticed in recent years is how other games have latched onto some of WOW's (and other RPG/MMO titles) fundamental mechanics. I think you could put up a strong argument suggesting that it's down to games like WOW, Ultima and Final fantasy etc that we find ourselves devoutly attempting to climb the ranks and brag to our friends and peers in games that you wouldn't normally associate that kind of system with.
Games like Modern Warfare 2, Halo 3 and numerous others. Can you imagine this back in the days of Quake 3, back then you didn't need any proof of your gaming prowess, you'd just let WASD and the left mouse button do the talking. And even that has changed with the introduction of Quake Live!

I already briefly mentioned Halo 3, for many there was always a strong desire to reach level 50 ( I never persevered) but Bungie are also taking this much further with Halo Reach, check out this link to see some of their impressive and I think exciting plans.
I guess one negative that does come to mind is that whilst all of these developers attempt to turn their games into huge time sinks, it leaves little time to mess around with other games so in that respect it could well be a very bad thing.
At the end of the day our desire to prove our superiority over others has well and truly been tapped into and I honestly believe that gaming in general is much more interesting for it. I just wonder where does it go next? I don't want to play one game for a year until the next one comes out, though the cynic in me tells me that's exactly what some developers want.
