note : I rate 0 the ones I don't like but that if I had to choose I would prefer over the ones I rate -1

Collapse -> 0
I can't come with more than one kind of game with this as a gameplay mechanic, and not better with this as a background story. This don't proves that other ones don't exist, but this means that we may have to rate a lot of similar games

Rock, paper, scissors -> -1
No, thanks. I really don't want having to code an AI, even very basic, in order to play against it at an antediluvian game which not entertain me anymore since I'm ten - nor having to rate dozens of RPS themed games (and what is the next step? tic-tac-toe? heads-or-tails?)

Alchemy -> -1
Meh. There are lot of games on this theme, but they are more or less likely the same
(also fits my comment for "Collapse")

Strange creatures -> -1
I don't like Pokemon that much that I would like rating clones endlessly, and as a solo ludumdarer I don't see myself having to make so much artworks in so less time - plus, for LD#35 I already made a game which could fit this theme, and I have absolutely not any single other idea

Edge of the world -> -1
It may sound silly, but: this theme implies that the game obviously includes a "world". And I'm tired of LD themes that implies a "world" - tiny, connected, small… No, not again, thanks.

Repair -> +1
There are so much things and concepts that could need a fix, and so much ways to fix something…

Build your own path -> -1
Same comment than "Collapse", plus limiting on something to build

Single resource -> -1
This is a better rewording of LD#44's theme, and somewhat connected to LD#52's, and I really don't want to redo nor rate LD#44 nor LD#52

Momentum -> -1
If LD was limited to professional game makers, this could be a good theme. I'm not ready to code nor use an advanced physic engine, and I doubt to be the only ludumdarer with that mood - plus, same last comment than "Strange creatures", with my LD#47's entry

Leave something behind -> -1
40, 43, and "Running out of something" LD's entries already have explored all the concepts that I can think of with this theme

Connected -> 0
Same comment than "Leave something behind" with 30, 41, and 44 LD's

Combinations -> +1
If only we had this one instead of the LD#41's infamous theme...

Isolated -> -1
Objectively it's not a bad theme, but my first LD was LD#22, and sorry, I can't…

Stronger together -> 0
Meh. Just: meh. Maybe this one will have a better fate than its so-common sibling "strength in numbers" suggestion we have almost every LD, in which case see my next comment

Sanctuary, Folklore -> 0
The only good thing I see if one of those wins, is that we will not have it anymore in the next LD's votes
