So, twist #1 was Billiards/Snooker, but now in 3D space! What's twist #2 then?
Well, your input can be described as two parts, right? Part one is that you select the angle from which you strike the cue ball with. Part two is the amount of force. Let's gamify part one; the selection of the angle to strike from. Maybe the cue stick can be represented by... I dunno, a ship? Or a mecha flying in space? Or... wait...I see something...I see...
Twist #2: Sonic the Hedgehog is now the cue stick. He has a homing attack, after all. We just need to make that move in a straight line here. As far as how much force is used, let's keep that simple and make it a matter of when you press the homing attack button, you freeze in place, and you hold down the button to build up force. Then let go when the force is as high as you'd like. For slight gamification of this aspect, maybe we'll make it such that to increase the maximum amount of force allowed, you need to collect rings. More rings, more max power. But most of the gamification is focused on the part of selecting the angle to strike the cue ball from.
So, you're controlling Sonic now. You're on the surface. The 'cue ball' object and the other balls/objects that need to knocked into the 'pockets' are all over the place, floating in the air. How do you get to the 'cue ball'? You run and jump around the place. Yes,
this is now part Platformer.
Obviously, it'd be boring if it's just a flat surface around. So there's terrain. There are buildings. There are platforms. Assorted objects all over the place. They, along with walls, can be used to ricochet the 'balls' off of. Stage motifs can be anything. Generic, or taken from Sonic games, or I dunno, even maybe a discotheque, with a giant disco ball in the center lighting up the place, complete with Sonic in a leisure suit...
Twist #3: Multiple participants active
simultaneously.
And yes, the participants (players, bots, or a mix of both) can interfere with each other. I dunno about being able to strike each others' 'cue balls', but definitely yes to being able to kick and punch each other in the face.
Honestly, at this point, if this were cross-gen, the only real difference between generations would be the sheer number of participants active and objects floating about
Would a large scale cooperative multiplayer boss battle mode work here? I think so. Sonic(s) (...and maybe & Friends?) on the ground. Giant space ship in the air. This ship, otherwise impervious to most attacks, curiously has certain weaknesses... like, think of a vent you can shove a photon torpedo down, but multiple of these. Use your 'cue balls' to knock 'bombs' into these holes dotted across the ship (yes, these would be the 'pockets') to inflict damage. Then upon victory, celebrate like it's the finale of the ID4 movie.
Incidentally, this idea is the addition to my list of games to
will into existence, as I mentioned to
@chocolate_supra here. Might need a name though...
Sonic Billiards? Snooker Sonic?... Snoonic? Snonic?
