Promotional anime made for Ys 4: the Dawn of Ys, not Mask of the Sun which are both essentially the same game but DoY released on the PC Engine (Turbographix) and MotS released on SNES. Also not an adaptation of Memories of Celceta. This was made essentially to see if any companies were interested in a YS 4 anime but no one was.

Author:-
Essentially 3 special episodes of the Mega Man cartoon that were scrapped because the cartoon's art style was changed from cool epic anime to yucky american cartoon. However, they were officially released by capcom for Rockman's 15th anniversary (in both english dub and sub!).

Adaptation of the Mega Man NT Warrior manga that's based on the world of Mega Man Battle Network. It's okay, but many probably have memories of watching this on Teletoon and other similar channels. I kid you not this has 4 more seasons after this, with the first one being another 50 episodes. No clue about game accuracy on those.

I'm gonna be real I have no clue, but I think it's an adaptation of Growlanser 4 of some sorts although it's just a single episode that was used as promotional media. They made 4 Growlanser games? What happened to Langrisser? Honestly probably doesn't matter.

Adaptation of Mistwalker + Akira Toriyama's Blue Dragon. Fairly sure it's not exactly game accurate. Has a 50 episode second season. This is actually a surprisingly known game adaptation anime from what I can tell.

OVA, 2011,
2 eps
Me:-
Author:-
I DIDN'T EVEN KNOW THIS HAD AN ADAPTATION I LOVE TRAILS IN THE SKY - 2 episode ova that crazily enough tries to adapt the entire first game in 120 minutes which is...not a good idea.

26 eps

Author:-
Adaptation of Arc the Lad 2. Game accurate for a bit, then goes full original.
