On the other side of the coin , people like me who feel loanly in a single player game and crave to play in a game where other real people exist.
I find all single player games (for me) are time limited in their appeal . I even end up looking for the cheat modes to finish the game . This is in part due to knowing I am playing against the software and to me, if that is all there is , is just pointless.
I like playing alone in game sometimes of course . It is theraputic to just be you and the game but there is something intrinsically souless about knowing you wont run into another human player, ever. For me it takes the joy out of gameing.
I recently start playing about with the latest release of Oblivion as it was cheap on steam. Ok for an hour or two but then I started to get seriously bored and wanted to have interaction with someone "real". Ok real is a loose term for avatar in game but at least you know there is someone on the other end of the code.
Do single games have a place ? Of course, the same way that flight simulator junkies like to build a fully working interior of a 747 in their shed. There is a place for all types of gaming .
Will single player games become more popular? IMHO definately not. Humans are social animals , notwithstanding the spotty teanager who thinks everyone hates them. Even the risk of "griefing" , (depends on your point of view and perspective of course) makes your gaming experience , if done right , more exciting (again a point of perspective).
Numbers itself prove that the multiplayer experience is more of a sensory winner . Those that play MMo's tend to play for years those that play single player games look for multiplayer after completing the content in said game,(or is that just me?).
I look at my past 20 odd years of gaming (sad) xwing v tie 2 years , Quake CTF league, jumpgate 4 years , SWG 4 years , EVE ongoing, Lord of the Rings online back every 6 months or so for a few months after 2 years playing, Jumpgate again for a blast and check all pilots going to play ED.
Single player, farcry 3 months total for all releases. Unreal same then a bit off UT. Few other sims totaling months .
The only single player game that ever caught me up and that was in part due to there being no multiplayer was of course Elite on the bbc then the amega. Jeez I lost my late teans early 20's to that game , THANKS DAVE! I should have been getting drunk
