R-Type Command (R-Type Tactics in Japan) is a turn-based strategy entry that requires patience but if you're down with that, the game can actually be rewarding and a lot of fun.
Long time R-Type fans will have to forget traditional shoot 'em ups.
Command is not a scrolling space shmup whatsoever, understand it's purely a strategy spinoff of the series.
If you enjoy Intelligent System's Advance Wars series or Hudson's hexagonal Military Madness/Nectaris
games on various platforms then R-Type Command is probably the right game for you.
There was also a sequel, Tactics II, released only in Japan.
It's much more difficult and not exactly import friendly if you don't understand Japanese.
Personally I'm getting back into Command's campaign after some years-- It's been part of my PSP backlog for quite some time.
I've also found the PPSSPP emulator runs Command fine but I haven't yet figured out how to successfully save a game yet.
Save states don't seem to work or maybe I'm doing something wrong.
I've also yet to try multi player, mainly because I don't know anyone else who owns R-Type Command so for now I'm getting back into the main game.
Once I finish playing the human side I'll get into the Bydo campaign.
