Sly Cooper cause reasons... to see sworn rival and eternal enemy Ratchet and Clank get all the love breaks my heart.
On a more serious tone.... Castlevania, Megaman (preferably X/origin story mixed) and Contra. All 3D and AAAA.
Studio competences of Sony's first party is mostly lacking for those games however. But third party could work. Fromsoftware/Bluepoint for Castlevania.
Platinum Games with Vanquish, and Housemarque with Returnal have working blueprints of sorts for both Megaman and Contra respectively. Gears basically being an even better blueprint for Contra - without the god awful controls, pace and animations obviously - something Housemarque's returnal is much better at, as is the gunplay and a hypothetical contra gunplay. Gears however nails a similar story synopsis with a dudebro cast fighting a similar invasion crises - the look, spectacle and setpieces if you will - the world overall...... even the choppers are Contra choppers.
Vanquish is literally Mega man without Mega man. What a gem of a game for the budget.
I hope you were watching the Dead Cells return to Castlevania reviews..... looks really good.
