My advice - GET'EM WHILE YOU CAN!
I took a look at some of the collections and like Scribd to a certain degree, it impressed me as copyright infringement central. I read an article on this TTS issue from a site called Rock, Paper, Shotgun (I swear, not making this up) and it seems smaller board game designers are split. Some are ready to send Cease and Desist letters (Fantasy Flight v NetrunnerDB), but most are willing to ignore the illegalities because a) they don't have the resources to pursue litigation and b) its defacto free advertising, not to mention good customer relationship building. What the GMTs of the world think I have no idea.
What I do know is that I saw a number of Bolt Action, Warhammer 40 K and other miniature fan produced DLCs. I can absolutely assure you that the 800 pound gorillas of the hobby, Battlefront/Flames of War and very, Very, VERY especially Games Workshop, will be mass producing Cease and Desist memos if they haven't started already. In particular, TTS at the very least circumvents GW's maliciously expensive miniature and paint range, and let's not forget, these guys are now suing private individuals producing 3D Print copies of GW models at home for their own personal use.
I've never been a GW fan, but I don't know how I personally feel about this. I do think, however, the end may well be nigh for the fan produced DLCs, so grab them now.
Yeah, it's true, some brands are very doucheb... proactive
in the defense of their content. Interestingly enough, it's always the companies that tend to sell super expensive stuff, while smaller game editors and mini makers tend to let it slide.
Plus, as an enthusiastic tabletop gamer, I don't see TTS as a concurrent to buying minis and rulebooks; in fact, it has 2 big advantages for the companies making these games:
-First, TTS allows me to "scratch the itch" and play a game I like even when I don't have people to play with around. This way, I don't get discouraged by the thought that I'm just spending money for nothing, and don't stop buying minis and other game related stuff.
-Second, it allows me to pre-test armies, which helps me choose stuff.
And I'm adding a last thing I just thought about: it allows me to show these games to newcomers, so that they may start enjoying these games, and begin buying minis and rulebooks themselves.
