Great review, MBC. Re: rituals, I think Icon relationships and the OUT can be used to flesh out possible ritual "seeds" (which is really what spells provide in the 13A ritual system) for a non-spellcaster who really want to use the ritual system. A rogue with 3 dice for the Price of Shadows should certainly be able to work some invisibility or divination rituals if he invests in the Ritual Caster feat.
Also, I think the Disease Track mechanism could be an excellent replacement for the "last gasp" save system, which I'm not particularly enamored with.
Also, I think I really need the multiclass rules from 13 True Ways to feel truly comfortable with the classes. I want just a little more granularity in the class builds to be able to customize the complexity level. Barbarians or paladins with maneuvers, for example. Something that isn't trivial to do like a talent swap currently is in the system. That's what I need to see before 13th Age becomes my go-to system, although it's already very close.
Hey TwoSix. Thank you. I agree with all of your points here.
However, as great of a system as it is , the inherent mobility of 4e combat + Forced Movement specifically coupled with the interraction of battlefield features/terrain/hazards + the ease of adjudication of stunting within that framework + the extraordinary depth and robust functionality of battlefield control is a very large draw for my group. We love all of those "fiddly" bits and all of that tactical depth. Its fun, it emulates how battlefields are dynamically mobile and, IME, martial forced movement is probably the single greatest element ever introduced to skirmish TTRPG combat (from both a genre and fun perspective). My life has been spent in athletics and martial combat sports, IME martial forced movement does more to accurately simulate the dyanamics of the two than anything we've seen to date. The full time loss of it would be hard to overcome so I'm uncertain at this point that 13th age could be a full time system for my particular group.
However, what I think we will likely end up doing is trying to have concurrent versions of the characters and their respective level in each system. Depending on the week, we may choose one mirror or the other to play out the session. Going between each system (and rendering character mirros) would be extremely easy IME. I think on weeks where we want to play out a dynamic, climactic BBEG fight, we would always use the 4e mirror, while every other week we could just as easily use either/or.
Or, we may just try play out our current 4e game and start a new 13th Age game after it resolves itself. I will likely playtest here and there and maybe grab some folks online (given that its fully TotM compatible) to play out a short campaign and estimate if there is enough crunch there for my home game players' tastes.
Regardless, great system and the 5e devs should be concerned about further segmenting of the pulp D&D userbase after its release. I can see a whole lot of 4e folks and folks who liked 4e but didn't like its forced movements and "fiddly bits" flooding this system with praise, dollars, and all-in support.
