Annihilation

[19683]

In t :His game, w :Hen particles anni :Hilate, t :Hey simply disappear.

Electron-positron pairs s :Hould generate p :Hotons, muon-antimuon pairs s :Hould generate electrons and positrons, and tau-antitau pairs can even produce
:Hadrons.

Dang it, I started a trend and now I half regret it
Anyway, I think it's not particularly needed. Even if they were added, they wouldn't do anything anyway.

In this game, when particles annihilate, they simply disappear.

Electron-positron pairs should generate photons, muon-antimuon pairs should generate electrons and positrons, and tau-antitau pairs can even produce Hadrons.

Actually, if you look closely when two particles annihilate, you'll see two photons racing away from the explosion (the little gammas).

Now, they do not make particles that you can use in the game, that is true. And that was a choice based partially on physics (it doesn't make too much sense to see a 'tile' of light standing still... and in general in the game, fermions are the tiles, and bosons are the rules). And it was based partially on game-play -- since the 'point' of the annihilation action is really to get rid of tiles, not just change them into different tiles.
