Hey all, can anyone tell me what games on GOG (other than Heroes of might and magic series) can be played as hot seat? Either designed or ad hoc.

This might help...http://www.gog.com/mix/local_multiplayer_splitscreen_hotseat_etc

The ability to have a multie-player game on one computer, either through an official "hot-seat" mode or just by one player taking control of two teams in a turn based environment (ad-hoc hotseat).

I know i'm just messing with you. :P

Thank you. I tried looking through Gog-mixes but could not find one like the one you linked. Am I blind or is there no Gog-mix search function? I know, but thought I would clarify in-case someone who read it, genuinely got confused.
I'm playing it in bed, so it's more of a warm patch rather than a hot seat.

There is none and that sucks. GOG has some kind of sick aversion to a proper search function with mixes and the forum...

There are a lot games missing in that.
I would at least add:

Balls of Steel (hot-seat)
Disciples & Disciples 2 (hot-seat)
Rayman Origins (local co-op)
Guacamelee! (local co-op)
Shadowgrounds & Shadowgrounds 2 (local co-op)
Adventures of Shuggy (local co-op)
Ring Runner (local co-op)
Megabyte Punch (split-screen)
Aqua Kitty (local co-op)

Hmmm... Hot Seat and not Heroes of M&M
From the games I own right now I can only think of these:

Expeditions: Conquistador
Alpha Centauri
Master of Orion 2
Age of Wonders III
Lords of Magic

I think Super-melee in Star Control II offers the best keyboard-sharing space duels in existence. If you want the game for free, you can download the open source port called The Ur-Quan Masters.

Here's some Super-mele duels. Notice how varied the ships are, with different attacks, movements and life points:

The controls as I remember them:
Turn left
Turn right
Thrust
Primary Attack
Secondary Attack

From those on GOG, Heroes of Might & Magic 2 & 3 and Worms still rank as my all-time favourite hotseat games.
You can throw in North & South but it's not on here.

I think Age of Wonders (the first at least, which is also the best one) also had this option ?
Alpha Centauri has it (I think it came with Alien Crossfire), but it gets too unwieldy real fast.

if You have the time, Try MAX 1.

Shit I haven't fired this one up in ages. But now I should work.
Must. Not. Install.

A few more to add:

Capsized
Hammerwatch
Octodad: Dadliest Catch
Pixeljunk Monsters HD
Pixeljunk Shooter
Risk of Rain
Serious Sam: The First Encounter
Shattered Haven
Spelunky
Super Puzzle Platformer Deluxe
Trine
Trine 2
Vertical Drop Heroes HD

I haven't tried any of these in local coop myself yet, so I recommend to do some research before buying.

Worms are the very essence of hot-seat and they are incredibly fun:
Worms United
Worms 2

(dunno about Worms Forts though)
