I think you might be a good shoot-em-up player, Joe, or at least above average! But yeah, while Sengoku Blaeaede is pretty easy I love the graphical style, characters, gameplay, music, presentation, everything!
I'm not so strict about 1CCing a game, but it depends on the game. For older games like Kyukyoku Tiger/Twin Cobra or Gunhed/Blazing lasers I'll usually reset it if I die more than once in the first 6 stages or so. For more frantic/casual games like the Psikyo shooters I'll usually start feeling bad if I have to continue more than 2 or 3 times to clear it. If I have to start credit feeding to get through a level it usually means I don't know the level/pattern well enough so I'll go back and play through it again. Credit feeding through a game just feels empty to me, aside from a few games from the Metal Slug series that I can't seem to complete without at least a dozen credits.
