Since Nick was inspired by old arcade games to make SK,

Were Demos based on the bomberman series?
In beta, They acted similar to the mechanics(Small charge click, larger hold), the cutesy design that are similar.
The bomberheads had several simerlarities to the bombermen, and the Blast bomb has a HUGE likeness!
And there is Blast Network! It's like bomberman!
Only thing different is the abundance of power-ups in bomber man and the lack of throwing bombs.
Eh? Eh?

This functions as a pretty good infographic. :3
Also, don't forget about Louies!

i would like they give us those costumes :c well as far i remember they told me for sure the bomberman will never make it as costume for spiral knights (i imagine due copyrights) but for the other 3 nick wasnt sure. but Link costumes i always see references on him in some games like Terraria or Dofus.

Wait, what? Blast Network is Bomberman? Since when?

Bomberman's bombs aren't bomb like, I think gunners were inspired by bomberman.

this is along shot but....Classic DOOM.
You fight monsters, find a elevator, go down, fight monsters again, find an elevator, go down till you find last level, theres a boss there!
