What annoys me nowadays is that the gaming industry is heading in a more user friendly, all age direction. There's a whole bunch of developers that are focused on creating games with good graphics, a cinematic experience, decent content but next to no replayability. Also alot of games are easier and more accessible than in the past.
This is good for the industry itself, because the income is so much greater than 10 years ago, but for the more hardcore gamers who want long and deep games like in the past, its really bad.
The best example of this change is Morrowind (released in 2002) and Oblivion (released in 2006). Now, theres only 4 years in between, but the change is huge. Bethesda went from an old school, unaccessible, yet very deep game with alot of content, to a game that is very focused on graphics, animations and a main storyline. The drawback with oblivion is that theres just far less to do in the gameworld, and everything looks the same.
If you take a look at games from 10 years ago, and games now, you'll notice how alot of games went from 40-50 hours of gameplay, to around 10 hours now.
And I agree with Doc for sure, too many games on consoles are focused around multiplayer. For example, when Halo 2 came out i was dissapointed because Bungie obviously spend more time on the multiplayer (which was very good, no doubt) than on the campaign.
The bottom line for me is, I'd rather play Morrowind, than Mass Effect. I'd rather play a game that has a certain amount of depth and takes some time getting used to, than a game that offers a brief cinematic experience.
The industry is attracting alot of casual gamers, while the more hardcore gamers are being left in the cold.
