They might be better known for the likes of Aleste, Gunhed, and Puyo Puyo but, like everyone else, Compile had to start somewhere. In their earliest days they favoured the Japanese 8-bit micros, eventually settling on MSX as their 'main' machine, and even this far back their focus was apparently on shoot 'em ups. One of the first was Final Justice, also one of the first games by designer, Satoshi 'Pac' Fujishima, and it was the first part of what would eventually became his trilogy - all shooters, all vertical-scrollers (kind of), and all available only on the MSX. Were there already signs of Compile's greatness this far back? Let's see :)

As gaming trilogies go, I can't imagine this is among the most popular or well-known, but as a shmup fan and a Compile fan, it's been a very interesting one to try out. Whether it's worth other fans seeking out, I couldn't really say. I suppose it really just comes down to how much of a fan you are. After all, the first part is little more than a tentative first step into the shmup world which itself was still finding its feet at the time, and the last part is more of a simple magazine freebie than a 'proper' game. Of the three, only the middle release - Guardic - is really worth spending any significant time with for genuine gaming enjoyment. It is enjoyable though, and quite original as well, so if you have an MSX (or indeed an appropriate emulator), that game at least definitely does come recommended.
