Well, I might as well give my thoughts. They aren't quite robustly supported at this point—we've only had one of each contest, so I'll be doing a lot of conjecture based off minimal data.

So far, RPGC has been shown to get a [i]ton[/i] of entries. This particular instance is probably in large part due to it being the first go for a long time, but I'm fairly confident that RPGC will get more entries on average. Why? Because it is far easier to get in, and the restrictions feel more casual. It also has a longer submission period, though not by much.

In addition, the review style is different between the two. Whereas RPGC relies on the community to review entries, TTL has guaranteed "moderator" reviews. Because of this, it seems to me that RPGC needs a dedicated review period, or there is too much of a risk of the entrants not getting any constructive feedback for their entries. TTL does not seem to have this problem.

For these reasons, I prefer the first option. As someone who likes the challenge posed by TTL, I would like to be able to focus on writing my entry without having to sacrifice RPGC reviews.
