This is probably the most critical decision to be made, and will have ramifications on almost every other part of the game. Some key points:
- Style: How closely do we want to mimic Homestuck's artistic style? 2d will almost certainly give us the closest approximation to this, but cel-shaded 3d might work as well.
- Combat: With 2d, we could have a Zelda-esque hack and slash, or a side-scrolling hack 'n slash similar to Odin Sphere. 3d, on the other hand, would allow for a 3rd person hack and slash, or a first-person shooter/hacker/slasher/caster type deal.
- Workload: While I'm not confident enough to say that 3d would make too much work for us anymore, I find it hard to believe that it would actually reduce the workload.
Note that the vote is there for convenience only so we can see what which people want at any given time. Feel free to change your vote/suggest new choices as appropriate. The vote is not there do decide a "winning" option; a good argument is much more likely to get an option used than simply having more people vote for it.
