Unfortunately, knocking it up a notch kind of puts me in some legal gray areas of what is considered 'free use'. Google has won some judgments regarding copyright infringements on storing and displaying cached data of websites. This makes me a bit more comfortable with what I'm going to do.
I will be importing data from quite a few large games sites into my search engine's database. What is cool is that I can automate much of it. In fact, game links will be added to the service automatically when those sites release new games. This will increase the value of my site considerably.
I think it's worth the risk. Hopefully, I can create something that will benefit the GameDev community, and it will be visible enough for them to support.
