I don't see how you can't like shoot-en-ups! The only problem with them is that they tend to be quite hardcore generally speaking when it comes to VC downloads. I usually play shoot em ups on my DS in the form of Big Bang Mini, Space Invaders Extreme 1 and 2, as well as Geometry Wars. Other than that I have R-Type TG-16 and Star Soldier R as downloads onto my wii
I must say however that I didn't like Bang-O-spirits, Nanostray 1 and XG Blast when I played them on other peoples' DS consoles. I also was crap at MUSHA and some of the Gradius games when I played them on other peoples' wiis/ps2s. I used to own Nanostray 2 but found that unpalatable too. ....so I've had my fair share of shoot-em ups which I DIDN'T like or sucked on (heehee).
Overall, I like em though!
