There are some things I agree with you on. The issue with DLC definitely leaves a bad taste in my mouth. I don't like the trend that is going with it, and when this DLC idea was starting to catch fire I knew it wasn't going to end good. An example of this would be MW2. Now, I'm not calling anyone here out, but still till this day I haven't bought either of the MW2 map packs. The $15 dollar price tag isn't worth it at all, most of the maps on those map packs had the original MW maps in them. Even if they didn't, it still wasn't worth $15 dollars. But, like someone said earlier, the reason why they keep doing this stuff is because mindless sheep keep buying it.
The other issue is the these "pre-order exclusives". I don't remember which game it was I think Assassins Creed 2, where if you didn't pre-order it from GameStop you had a humungous part of the map completely blocked off.
Now, the issue with multiplayer, I disagree. I think that playing with others just can make any game 10x better. Same example , MW2, I was on the verge of selling or trading in that game, found a site where people share gamertags, and it turned out to be one of the most fun games I've played this generation. It's just the overall social interaction that accentuates the competitive multiplayer gaming.
Now, if games begin to have monthly fees, that is when I will stop playing videogames.
