Almost a million games now and this place is becoming impossible to search. You can't scroll the entire list of any genre even with subgenre or art style tags... your browser will crash before you get even halfway through.
Your interface needs massive retooling, and you should look to AnimePlanet's interface as a model. Search by year, genre, subgenre, tag, and most importantly a return to pagination. Also reviews on multiple metrics. The design is antiquated and inadequate. Trash it.
