Given that all four of these games have previously been widely available elsewhere, including on Steam and as part of Evercade’s Toaplan Arcade Collections (Zero Wing is on Toaplan Arcade Collection 1, Batsugun & Vimana are on Toaplan Arcade Collection 3, and Dogyuun is on Toaplan Arcade Collection 4), we predict this one will likely prove to be a much harder sell than some of the other collections Polymega has released in the past.

Maybe. But still, good idea mixing it up for the collection.

Batsugun is the better Toaplan game, so it can carry the other 3. Dogyuun is gorgeous, Zero Wing has the meme factor, and Vimana is seen as the weakest entry. Buy it for Batsugun and get a few extras. Shmup players have dropped cash for less.
