Gekioh Shooting King/Shienryu (PSX) - It wasn't very innovative when it came out but looks awesome and plays very well. The SAT version considered as the best original home port but I'm good with the PSX port for now, I mean, yeah, the original (and SAT port) loops after the endboss and the PSX version doesn't but I won't make it that far anyway so no complaints from me here.
ThunderForce V (PSX) - Love it since day one, awesome game, challenging, looks and specially sounds great, a real treat.
ThunderForce VI (PS2) - I like it, not the greatest TF game but solid overall and just fun to play. Keeps me on me toes.
