Go play them then but don't assume every one wants the same thing as you and don't live in the illusion that simplistic game play can cut it for the mass market today. When I was younger, tetris, pacman, mario, sonic etc. were all fun, very fun for me to play in fact. However, simplistic games can only go so far. Now for my serious money ($50+AUD) I expect a great story, excellent voice acting (this is actually very important, voice acting can ruin a game), sound effects and then also great game play and top notch graphics. Great gameplay alone doesn't cut it for me anymore. A game without a story isn't worth the time for me, a great story needs great dialog and a game with bad voice acting no matter how much it excels in other areas can be terrible. It's not like before where good gameplay alone is enough. Back then game developers only needed programmers and maybe a background musician. Now games need everything else and that means they need to hire not just programmers but also writers, actors, musicians (midi music doesn't cut it anymore). That increases the cost of the game, but it also provides jobs. Now it would be great if all game developers can make great games. However that's unrealistic. Just like everything that involves creativity, for every good work it is preceded by many bad works. It is experimentation and learning (take for example Too Human, they tried an innovative way to control the character - many found the controls bad, now many developers would know to steer clear of that control method or to improve it). Sure I will still play simplistic games, and will enjoy them. But those games better damn well be free (ie-Flash games) or cheap (iphone games -- less than $2AUD). But if the two types of games were mutually exclusive, I would prefer to have the big blockbuster games that breaks new ground (albeit expensive) rather than the cheap simplistic games (that are mostly a rehash of games already released).
As for tie-ins and those kind of games, I personally don't enjoy them. But do I get pissed off that I think they are priced much more expensive than I think they should be? No, why? because I wouldn't buy them even if they were $5. But other people do enjoy them and do think they are worth the price they are being asked for (hence they buy them). Do I have the right to say that they should get rid of those games simply because I don't enjoy them? No I don't. And as for DRMs, if pirates didn't pirate there wouldn't be a need for them. Developers develop DRM because they have mouths to feed so more power to them.
