So what I am gathering from this thread, and from this quote on the HCG101 article,
" You would think a horizontally scrolling shooter on a system with tons of competing shooters would have to be pretty good to stand out. Nope. Deep Blue is not only the worst one available on the TurboGrafx-16, but possibly the worst of any to be released on a major game system. "
is that I should avoid this game until I am looking for something new to play and have played many other shooters. I currently only have Dragon Spirit on TG16, and someone had suggested I get Deep Blue - but now I am suspicious it was sarcasm
