100% agree!C'mon now. FM Towns looks appealing but is not comparable to the Sharp X68000 library.
4 Gradius games, Castlevania, Cho-Shen Ra, and a long list of shmups and fighters to boot..
Let’s be real
But when it comes to Gradius games on x68000 there are much more;
Gradius
Gradius 2
Nemesis 90
Nemesis 93 Kai
Nemesis 94 Kai
The new Gradius 3 Port (insane!)
plus the rest of the family (Salamander/Parodius/Twinbee)
plus one sprite change game of Gradius but I forgot the name

Also there is no R-Type on FM Towns and Mahou is unplayable on Marty.
More Ram will not help neither does HDD installation.
There is one known RGB mod for Martys, a german guy did win one @Amiga Joker if irc.
It came fully modded, i postet pictures in the FB group years ago.
Problem is, he does not sell or show it again. He even did blew the PSU by plugging in directly.
When it comes to the Towns experience, there is no reason to go for Marty.
Even the worst computer is better.
