Hello all! First, I'm new to this forum and new-ish to the game. So, having the Core and Human Sphere rules as pdfs is a huge help to start playing and I'm very grateful for CB putting up all the rules for free! I'm quite interested in the fluff too, so, I'd buy the physical books anyway, but for starting, it's great to have the rules at least! However, the lack of any bookmarks in the pdfs is making them really unwieldy during the game, especially, since there's much need for back-and-forth referencing and looking up rules, as a new player. Are there any versions of the pdfs with bookmarks I'm not knowing about, official, or fan-made? If not, could we encourage CB to update them, with bookmarks? Thanks!
In all honesty, using the wiki (http://wiki.infinitythegame.com/en) is more effective for rules referencing. The PDFs are great for reading through and getting the themes of how stuff works.
The Army Builder also hotlinks to the wiki page for certain rules, which I found a really useful feature when I was learning the game. There's also apps like Infinity Helper and Mayanet (the latter is sadly fruity fondleslab exclusive) that provide an offline version of the Wiki. I haven't opened the PDFs or rulebooks in a few years, truth be told.
