Dear Navid,
I appreciate your efforts at trying to clean up some of the ubiquitous game-related articles. However, for most of these articles, rather than deleting them outright, it seems more appropriate to merge them into the main game article. (e.g. Roll (Mega Man) into Mega Man). See the guideline WP:FICT for details. If you are unfamiliar with creating a merge & redirect, I'd be happy to help.
