Yeah a full picture of the table with the game set up to start would be nice, too (maybe even with labels).
This leads me to something I think is missing on BGG (or at least isn't done in a way that I'm looking for): Quick rules refreshers. I have a lot of boardgames. I actually enjoy reading rules. However, for many of them, reading through the rulebook is a twenty minute affair. And that's when you're not trying to take someone else through the rules. When I'm sitting down to play (or mid-game), I'd like a really quick list of rules boiled down to the simplest of facts. These shouldn't be the kind of thing you can read instead of the rules. You still have to read the rulebook first, but when you get ready to play, it gives you a quick overview of both the main rules and things that are easy to miss or forget about.
I've seen
Headless Hollow, but even these are more detailed than I'm talking about. This is something I wish I could do myself, as I think it would be invaluable for a lot of people, but it's just not my forte.
As for reviews, I'm actually in favor of quick hit reviews, where you don't do a whole rehash of the rules and just get to what worked and what didn't and final opinions.
I think the idea of doing reviews of boardgames that have been based on video games is a good one and a natural fit, but it's also pretty limiting. There are a number of them that are really good, but they've been reviewed quite a bit already. And it's a niche of a niche market. A series of articles like that would be great, but it should be clear that it's a series and not the main drive of the site, I think.
