It was mentioned a long ago, so I'll summarize it a little:
I think the favorites system is sort of messing up the front pages in these ways.
1. Class/Friend/Fake favorites. Games made popular this way are creeping up the pages, getting to the 2nd or 3rd page just because they have an education account or are using it together. Just look at page 5. I think favorites should determine how good the game is, not how many friends you have here. A lot of indie games, like Starblast series, are struggling up the climb while classmate favorites swoop them right up to 15. There's a reason why they never really climb anymore, because they're not really good at all.
2. Favorites system is like a competition. To make your game be in the front page, your favorites have to be higher than the other games. Why would kids want to fall down by giving others a condition they need to win? They huddle in groups and raise their own up, no matter how bad theirs are. And the separate users don't want to fall behind either, so they just don't favorite many games, unless the projects really moved them.
3. The problem with bad games in the front page is, people won't easily get inspiration. Who'd want to build a game like "KYS" or "Adventure", honestly? People who make crappy games get more attention than the ones who are actually better at making games than them. There are games rotting at page 270 because they never got any favorites but are actually pretty GOOD. People don't get to see half of the decent games because they're not up front. I feel like Starblast, and some of Latif3's games (he makes great games, just doesn't show them off) should be noticed
So... yeah. That's my post. I think FG would make Flowlab better. Favorites still SHOULD be in place, but maybe there could be a "Featured games" button and it'll move you to a whole selection of carefully chosen games.
