I'd recommend 'Sine Mora' too. it's an excellent shoot em up. Also there are some excellent games to be bought from XBL Arcade, and most have demo's, so u can try before u buy.
Take a look at the XBL Arcade games thread to see what other's recommend.
Are there any Side-Scrolling Shooter games like in the old days of Gradius?
There's way more vertical shmups than horizontal but out of the few that are available one of the best I've played is Deathsmiles. Also check out Akai Katana, both can be picked up cheaply, we were lucky to receive western ports of these games thanks to RSG. On XBLA I can't recommend Trouble Witches Neo enough! if you like hori shooters you have to try it. It has a very cute visual style but some brilliant gameplay.

You need to try Sine Mora on xbla. It's brilliant.

Well I was kinda on about actual Xbox 360 games not the LIVE part.
Do you mean games on disc ?.
