I have yet to see the Tome of Knowledge, but I am excited about it. For years, I have been asking for a game to track every kill and craft, and make that information available to the player. Tossing in titles appeals to my badge whore nature; tossing in lore makes it a Civilopedia. Grabbing my favorite info features from Fallout and Civilization is a good thing. If you can make your game’s data or economic system closer to EVE’s, you probably should.
The Tome is imperfect, I am told. Fair. As noted, this is the kind of thing you want to get right at the start, because you cannot go back and retroactively collect data. Some games have logs they could mine like that, at great effort and expense, but it usually starts counting when they know why they would want to count that. As a small example, the last Lord of the Rings Online™: Shadows of Angmar™ added deeds to existing areas, to mixed joy and irritation from players who knew those areas well from running them dozens of times. I hope you like BG the first dozen times, because you’ll need a dozen more to get all the deeds done!
What do we want recorded in Warhammer or any MMO? You can work out display and interface issues later, but you must decide what gets kept now. Track every kill and craft, ideally noting if the kills were solo or in a team. Have some detail on the kills, so the game can distinguish between a soloable monster and a public quest-ending monster of the same species. It apparently tracks times that you target yourself, what has killed you, and so on. Stellar. If it can also track things like how many arrows I have fired or how many times I have been set on fire, great. TF2 accomplishments could be a fun place to look for some ideas.
What sounds like it is missing, that might be interesting to have, is robust information on leveling (and, to a lesser extent, quest completion). You only level 39 times, so jot down some information. You leveled on Tuesday, October 14 at 3:27pm, from defeating an Ironbound Juggernaut; you were in a team with Bob the Engineer, xXxShadowAssassinxXx the Witch Hunter, and Elithwyn Graceleaf the White Lion. Please, toss in what details of the moment you would like recorded just then. Stats and items? Tobold talks about recording your personal story, and leveling seems like a relevant time for a journal entry. You could do the same with quest completion, noting that you completed public quest A at date/time X in a group with Y along with Z other players taking part.
