I miss the time when most games allowed a second player to help with the game. Games like Double Dragon, Kirby, Perfect Dark 64, Contra, and ESPECIALLY Bubble Bobble. I grew up playing games like these with my brother, and through teamwork and cooperation we could plow through these hard games. Then we would play them through again and try to sabotage the other person's score and/or try to get them killed. Games don't have that any more, the only recent game I can think of with this function is Army of Two, and the two player function wasn't anything special.
I also missed the games that were just games. The ones with little or no back story. Where you go around beating people up just because you can. The original Double Dragon is a perfect example. "Some guys kidnapped your girlfriend, go beat them up". Now, every game that could fit into this category has a last minute prologue and weak storytelling segments that are supposed to give you a reason to keep playing but end up doing nothing but bore you and motivate you to look for a skip scene button. There won't be one, so now you have to watch as archetypal NPC #4 exclaims "we will destroy you in the name of justice!"
Games like DMC4, if you skip every cutscene in the game, would be a good example if this didn't make the game 4 hours long.
