Are there any more scenarios other than the three in the rule book? Any campaign rules? I'd like a little more to play with than just straight up dogfights.
Scenarios
All of the game 'big ships' and Aces boxes contain new missions for your X-Wing games.
- YT1300
- Firespray
- Lambda Shuttle
- Imperial Aces
- Rebel Aces
- YT2400
- VT-49 Decimator
Also, both Huge ships available at the moment contain a mini-campaign mode with several linked missions.
- CR 90 Corvette
- GR 75 Transport
The big box expansions (Aces, Freighters, Shuttle, Deci & epics) come with scenarios
Bah! I was planning on only keeping to the small ships, I may need to rethink my budget! 
Thanks for the replies though! 
There's also the X-Wing Mission Control - player created scenarios.

Ah, now that's more like it, excellent thanks. Although its a bit of a shame you can't filter out scenarios you don't have the ships for. My collection is still somewhat limited so its tough to find ones that only have X-wings and TIE fighters! LOL Still, I'm sure I can get some ideas for my own scenarios
