I’m just curious, I’ve searched all over for a video game database that includes a “keyword” or “tag” search, not just a title/company search.
For example, if I wanted to find all the games with a character named “Bob”, a city named “Funkytown”, or all games that use a particular kind of magic (elements, psychic, etc). Where would I go?
I know about Neoseeker, and it’s close to what I’m looking for. Is there anything better? Something with a “tag cloud” maybe?
Yes, Google is great, and Wikipedia is usually helpful as well, however I’m looking for something that is strictly video games.
I use gamefaqs a lot, too. Good suggestion, still not what I’m looking for, though.
