Forgot a couple from before, one of them in particular i really wish they would at least port to modern systems.
Viewtiful Joe 1 and 2 (PS2/GC) - One of the greatest capcom games ever yet noone ever talks about it anymore. No idea why, game was brilliant then, brilliant now, and did a spin on the side scrolling beat up genre that hasnt been done again since.
The Getaway (PS2) - This one is flawed i admit. But a lot of its flaws were due to the console it was made on, not because it was a 'bad' game. A game ahead of its time, attention to detail was insane. All they needed was a more traditional health system and an actual map so people could tell where they were driving to in between shooting sections. Great story, good voice acting just made on a system that could barely handle it. Plays much better on emulation via pcsx2 now than it ever did natively ironically enough.
Maximo - Ghosts To Glory (PS2) - Hard as fark 3d platformer that was a hell of a lot of fun to play. Not that much else to mention.
Skies of Arcadia and Skies of Arcadia Legends (GC/DC) - Another RPG locked off modern consoles that at the very least deserves a port. Brilliant rpg, and well worth checking out through dolphin.
Legacy Of Kain Defiance (PS2/XBOX/PC) - I mean you could have Soul Reaver 1/2 or the OG Blood Omen here but i feel this game was the best in the series yet gets mentioned even less than those three. Brilliant Game, only think that kept it from being a masterpiece was its somewhat iffy camera that would obscure you when you were fighting at times. Otherwise, great graphics for the time, great story, incredible voice acting, level design and a great feeling of progression where you feel like you got gradually stronger as the game went through.
Final Fantasy VIII (PC/PSX/Switch/PS4) - Some people are going to laugh at this inclusion. It's a final fantasy game, how the hell is it underrated? Thing is, whenever people talk about brilliant 6/7th gen FF games everyone goes to FFVII/IX/VI/X. Noone seems to ever mention 8. Was the junction system hard to get used to at first? Sure. But it also had by far the best mini game in the entire series (triple triad), good characters, amazing graphics for its time and for at least the first half and end of the game, a great story.
Resident Evil Code Veronica/ CVX (DC/PS2/NGC/PS3/X360) - Seems to be trendy to shit on this game in recent time. Mostly because of its difficulty, the tank controls (which noone has a problem with when they replay REmake or OG RE2/RE3) or because Steve had a whiny voice. Truth is, gameplay was awesome, had the most OP knife in the series, one of the best soundtracks in it and it lasts longer than a couple of hours unlike the other old OG games. Good variety of weapons, actually FEELS like a RE game unlike everything made since RE4 and the Wesker cutscenes are the best in the series. Canon to the series, crucial to the following games storyline wise and most deserving of a remake out of all the ones left that havent gotten one.
