I also want to give a mention of G-Darius, the first shmup I ever owned for a home system, bought from the discount bin at a Toys R Us because I had a friend staying over and didn't have any two player games for my Playstation. Turns out it is amazing, and definitely kickstarted my ongoing love of the genre. Although I've sampled a lot of other Darius games (I love the music and the fish), I still think I prefer G-Darius over all of the others. Dariusburst Chronicles has an insane amount of content but disappointingly (to me) still didn't include the G-Darius style enemy capture system which adds a lot of depth compared to other games in the series, and the beams aren't big enough. I am very excited about the upcoming G-Darius port!
I like the Darius games in general, but its mostly for the aesthetics (especially Gaiden/G-Darius/Dariusburst). The gameplay and scoring is a little too basic for them to be my favorite shmups overall, but the aesthetics definitely make them my favorite shmups to play stoned.
Sidenote- I had the opportunity to play the full size, sit down, multi-screen arcade cab of Dariusburst at a barcade in Denver and it definitely gave me more appreciation for the spectacle of the series which is really lost in home releases. If you ever see one, I hope you give it a shot, even if you aren't a fan of the genre.
