Ghost Pilots is one of the best 194X clones out there but there are 2 glaring problems with that game.
1) Too many cheap hits and mandatory deaths.
2) No powerups when you die and you always start at level 1 firepower after each death.
At least ultra-hard shooters, like DoDonpachi, Batrider, any Atlus/Cave/Raizing shooter, gave you POWs or a full POW when you die.
I like Last Resort far much more, primarily because I'm a big fan of R-Type and the graphics are dark and gloomy - sets a great mood! The continue points do suck dog, I will admit.
I don't need 99 men to finish the game, however I do need to use the "unpiloted" 2nd player with a couple of bosses. It is a hard shooter - but fun!
