Well do tinkers create tinker data most? The tech tree is, unsurprisingly, very tinker heavy. While our host don't have to be traditional tinkers, we should be very liberal with tinker themes. That could help.
It would be possible to invest into Thinker data and go Dragon route? Or create our own Tony Stark. Someone who doesn't create tinkertech, but either perfectly understand it or simply Thinker power increases their intelligence to the point where they create super science ala Tony Stark or Reed Richards.
This is why unless we get someone like Masamune, who can mass produce tinkertech I personally don't find Tinker route that efficient unless it would be something that may self-replicate on it's own even without host (like nanotechnology). Thinker focused on technology may be the case. Now when I think about it AU story about Accord who focuses on being engineer would be interesting in this case.
Creating host(s) which can actually improve society as their technology is far, FAR easier to replicate may be one of the main long term goals. And if there is something that may deal with Scion, it's Super Science. Now to only survive beings like Simurgh and Mannequin before escalating with technological might here...
Re: Information et al - One of the weird ironies of this quest is that you tend to collect the most Information of whatever kind your Host uses the most.
So as I mentioned going 'Dragon route' with heavy focus on increased, possibly escalating intelligence and lots of Thinker research may actually be an option, hmmm...
Also, we can go to DBZ universe and become a Super Saiyan God. That would solve our problems. It feels like cheating though.
It depends if 'game winning' strategy here is to rely on few god-tier units or create something that forces whole groups/societies to unite and fight one big bad, which is kind of what happened in canon. Command & Conquer, Supreme Commander, Stargate, Starbound, Total Annihilation and few other dimensions where focus is on LOTS of individually weak, but together absurdly strong societies which can deal with lots of top tier enemies.
Both may be viable, although second one may require set-up and build-up time to truly shine, which on Earth-Bet with soooo many enemies may be tricky at best.
Of the new options I lean more towards magic since I feel that it will lead to us rezzing people and making the Shaman power viable..
I agree with magic. Super Science can also work.
Thing with magic is that esoteric very exotic effects and dimensional shenanigans (which magic can easily provide) is simply best way to deal with enemies like Endbringers and Scion.
