Activision - Does not allow derivative works per their terms. See 3. License.

Codemasters - Does not grant permission to monetize videos. Posting videos is accepted.
GungHo Online - These guys do stuff like Ragnarok Online. Videos OK, monetization not OK.
Microsoft - Videos are completely fine as long as you are not paid. They say part of this includes Halo in their rules, so Bungie may or may not still get on your case. Check out the rules here.
Natsume - These guys are famous for Harvest Moon among others. From an email they allow videos without monetization.
Naughty Dog - The Last of Us, Uncharted, Jak and Daxter… great games, but they don’t want you to use ANY of their footage (said via email).
Nintendo - Encourages videos (especially Let’s Plays), but may decide to monetize your video. The exact wording is on Go Nintendo.
NIS America - Famous for stuff like Danganrompa and Disgaea. Encourages videos, monetization not allowed.
Rockstar / Take-Two Interactive - Encourages videos unless they are just straight cutscene footage (Let’s Plays with cutscenes OK). Pretty sure they don’t want things monetized. See the full rules here.
Sega - Does not give any license for YouTube footage .
SNK - They do not give license for derivative works.
Square Enix - Does not grant individual permission to use their works, but DOES grant permission to larger entities. .

TellTale Games - The Walking Dead, Wolf Among Us, Sam and Max… these guys have some really good stuff. Let’s Plays are definitely allowed, monetization is not. See this permission post on their forums.
