Schmups.

Its an acquired taste, for the most part. Too much going on on the screen can make anyone a little dizzy, and they take precision to master. Each game is different, and so the bullet hell can be easier to work through but complex looking, or fill the screen and take a certain path to get through safely, and the path is hard to see in itself. 80's gamers like myself, who've played Gradius and R-Type to name two favorites (Raiden coming in later I believe?) these games are treasures.

Schmups aren't meant to be long and drastic. The only replay value they have is scoring, more often than not.

If you feel like it, sure.

Its uniquely named to be certain. It's a shame it only has local co-op, but things can change at some point.

I'm definitely gonna find out tomorrow when I get done with my daily stuff as I'm about to head to sleep for the night as soon as some of this stuff finishes up.

Yup, Jamestown sure has a strong (Do)DonPachi feel, especially with the first ship and the beam weapon and those long strings of enemies on the first level.

Also it does get close difficulty wise once you put the difficulty up (to unlock later levels). Unfortunately it also introduces some fairly unfair-ish dodging bits in the final level, the likes of which the Donpachi series has luckily avoided.
