not just allowing hornyposting... BUT ENFORCING IT!
banning fanboyism [for Nintendo first and foremost to get rid of the "NintenFAQs" stigma once and for all] so the bigger and more varied user groups can enjoy their time here, that would help immensely
heavily reduce and optimize ads so they aren't bloating the code, data transfer, memory usage, processing power and screen real estate
divide up separate versions of games again so one name doesn't cover all versions
make it A LOT easier and less convoluted to submit game info, reviews, screenshots etc., it shouldn't take several weeks for details to be posted after users submit them
Kill the legs first, that's an ironclad battle tactic!
