Re: What games are you playing currently?
ODST is neither too short nor too easy IMO, especially if you don't have that much experience with the previous Halo titles. Plus, it introduced Firefight, one of my favorite multiplayer modes. It has great atmosphere, the VISOR, audio logs that tell a compelling story, great additions to the weaponry, it comes with all of the (previously pretty costly) Halo 3 multiplayer map packs - it's great value and my third favorite Halo title besides the original and Reach.
Not to mention the audio-treat for Firefly fans
