I'm running a university research lab interested in improving how we organize and access interactive media like games and apps. Towards making a prototype search engine that understands the interactive content of games rather than just their metadata (e.g. title/description/tags), we are making a crawler that will download and automatically play the first few minutes of every game we can find. Can we coordinate with you so as to not interfere with site operations or throw off download counts?
Here's one of our recent research papers on the general idea: https://adamsmith.as/papers/crawling-indexing-retrieving.pdf
In an idea world, the search system works like Google News or Google Books. Just as these tools can determine that specific articles or specific pages in larger books are relevant to a user's information need, a game search engine can tell them that specific modes or moments in a game are relevant to their interest. The search engine doesn't host the content -- it redirects to some other site where either the user needs to pay for access to the game and (where supported) they can follow a deep link into a specific moment for supported games.
