* Probably

Over the past twenty minutes I have had a gestating idea for what I consider to be one of the Best Games Ever™.
Perhaps other people might have their own nuggets of a game concept that are worth discussing, but I thought I'd throw this out there as something novel.

My idea is somewhat inspired by Nintendo game design in reverse, and with my superficial understanding of the concept behind Sega's Dororo: Blood Will Tell (apparently based on a manga). The core concept is that you start off with all your gear - your character is very powerful, can think, fight, survive all kinds of situations. Kind of like Metroid Prime's initiation. However, instead of losing your abilities in one foul swoop, you lose them one by one and it's essentially your choice as to which abilities to jettison.

(Macguffin time: let's just say for sake of explaining the concept, you have a fancy space suit, you crash land on a planet/moonbase/alternate dimension and thanks to your activity, your suit can only support diminishing numbers of  functions as the game progresses.).

Initial functions you would start off with might include: jetpacks, double jump, regenerative healing, gun proficiency, swordfighting, stealth camouflage, temporary invulnerability, hand to hand fighting, sniping.

You start the game able to play in any of those types of modes as you see fit, and then after the first boss, you have to sacrifice one of those abilities and you can choose any of them as you see fit. So, conceivably by the final boss of the game, you might be down to just the ability to heal yourself - and said final boss might be some immense titan who can only be defeated indirectly a la Akido - using their momentum against them and baiting them into running off a cliff/into lava/electricity/etc. Alternatively, should you have opted to keep stealth, you might have to try and climb them to reach a few weak spots to neutralise.

I guess the purpose of such a setup would be to force the player to alter the way they approach the game as they go through, rather than ending up becoming an overpowered force at the end of the game with difficulty increases purely courtesy of bullet sponge enemies appearing more frequently. You might start out playing it as you would approach and FPS, then decide that you could do away with that so long as you kept increased vertical mobility and sniping abilities. Then you get forced to sacrifice one of those and the whole balance of how you play is upset.

Does anyone think there might be some merit to this concept? I, of course have no means nor ability to bring such an idea to fruition, but thought I might put it out there to see if others have other ideas they'd like to share.
