 Please stop adding inappropriate external links to Wikipedia, as you did to Game engine. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Since Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you will be blocked from editing Wikipedia.   
If this is a shared IP address, and you didn't make any unconstructive edits, consider creating an account for yourself so you can avoid further irrelevant warnings.
