How to only get "game" results

I tried

http://www.giantbomb.com/api/search/?api_key=[API-Key]&resource_type=game&query=Team+Fortress+2&field_list=name,image,description,id

But it returned video results as well.

Is there any way that I can filter this so I only get Game results? I could do it in code, but I'd rather have it rely on the API.

@ron975 use resources instead of resource_type: http://www.giantbomb.com/api/search/?api_key=[API-Key]&resources=game&query=Team+Fortress+2&field_list=name,image,description,id
