Since this thread is kinda silly, I don't feel bad derailing it and going off on a tangent.
I've always been intrigued by the SGX, particularly to try out Aldynes and 1941 (and Ghouls and Ghosts to a lesser extent). I used to be put off by the cost of entry, but nowadays, particularly with flash carts available, my main concern is lack of space available in my setup (although I can make space...).
So the question to the experts here is: where do you rank the SGX games in comparison to the PCE and CD shooters? Are they in the top tier league, right up there with Gate of Thunder, Lords of Thunder, Nexzr, Soldier Blade, Super Star Soldier and Spriggan (or insert your favorite here)?
