I was browsing the APH forums one day and got an idea. Wouldn't it be handy if the best threads were in one place? The place would be called "Recommended threads" or something in those lines. This would get the good, creative, interesting or just plain fun threads the attention they deserve. And the people that post there get responses, which would strengthen the community. The recommended threads could be great to newcomers too. They wouldn't just request a couple of games and leave.
Another idea I have is the addition of game collections. A selected individual or individuals, of course, would collect games to individual folders by theme, gameplay similarities or overall quality. This may not be a revolutionary idea, but I think it would be kind of cool to see this happen. Here are a couple of game collection suggestions. (try saying that three times quickly)
Underrated games
Stickman games
Funny games
User favorites
Zombie games
Flash-games you should play
...
My third idea is the addition of a way to make threads directly linked to games. For example: I play a game called The Last Stand: Union City and want to start a thread about the game. Under the game is a button to start a thread directly linked to this game. Underneath that button would be a list of other threads connected to the game. I understand that is the place where comments go, but I still stand by my idea. And of course the threads could be viewed from the Forums, they might actually have there own sub-forum.
