Powerpoint is Microsoft trademarked product. If you make profitable (google ads?) site with MS Powerpoint templates or try to sell it, you could easily lost that domain. I dont say it will happen, but is it worth the risque? Better to put your money and time into developing sites which not infringe any TM.
And remember, registering TM domains makes all domainers look bad - in the long term, that can reduce your profit as a domainer or web developer.

Lips is popular, motion sensitive, MS game (and you know that). If you ever put any kind of generic advertisment on that site, at least one of them will lead to MS product and they'll be able to take domain from you if they wish. And without advertisment, I dont know how you can monetize this domain, so I would say you lost your reg fee money.
If you hope Microsoft will bought every 3D domain matching their games from cybersqutters like you, well... keep dreaming.
And stop to justify your TM registrations, you are giving very bad example for a people who read this thread.
* Take this as friendly advice, I lost lots of money on TM domains when I started domaining, and, looking back, I feels very stupid about TM domains I registered. I even reged McDonalds.TV after couple of beers (I contacted them later about giving them domain, but dropped after didnt receive any replies). And I'll repeat myself: Registering TM domains makes all domainers look bad - in the long term, that can reduce your profit as a domainer or web developer.
