Halo 3: ODST
The best of the Halo line so far. ODST takes you to the human side of the fight against the Covenant taking place before the days of Master Chief. The side effects to letting your loved ones get this game can and will show up at odd moments during the day.

Side effect includes:

1. Randomly yelling about stupid grunts being dumb.

2. Upon the completion of simple tasks using the words epic, legendary, owned, overkill, and/or random muttering about how one 'pwn'd' that shit..

3. Total lack of any kind of attention to the every day life around them.

4. When talking to someone about anything they make reference to something that Master Chief would do in that situation.

5. The forgetting of important dates due to needing to reach 200,000 points on Heroic Lost Platoon for the achievement that will finish off all 8 lvls they have been needing that for.

6. The noted drop in grades going from A's to D's because they wrote a paper on the subject of how Buck was the best player in all of Fire Fight and could easily get way more kills in real life then Sgt. Johnson.

Teacher: Well Mrs. Doe your child got that D cause he wrote this for his report on his hero..
Paper: Buck so would have killed like 40,000 brutes before Sgt. Johnson could have even lit his cigar. If I could be anyone when I got older it would be Buck from the Orbital Drop Shock Troopers squad,
Teacher: I think you might need to put him in counciling for video addiction.
