Console advantages:
- Less cheating.
- Everyone uses the same hardware so it is an equal playing field.
- No hardware or software compatibility issues.
- Xbox Live and PSN are much easier to find friends to play with.
- Sitting on the couch.
- Renting games is also easier for console.
- My friends at Activision tell me that the 360 is the lead SKU again which means that the devs will have given it the most attention.
The only genres I prefer on PC are RTS and MMOs.
