The tutorial is very restricted and the aim was to introduce people who don’t know anything about tbs games to the idea.
@Equisilus, if you want to “turtle” then your best bet is to play on Lord or below, so you can play around with the systems until you figure out the mechanics, and the synergies.
People say you can’t turtle, but that’s not strictly true. It’s more straightforward to not turtle, if you’re playing with default victory conditions, where you have to kill the enemy Leader and capture his Throne, then you’re going to have to get out there eventually.
Plus unit upkeep is quite expensive, so you need to be capturing and holding resources.
If you’re playing against the AI then it’s much harder to turtle, especially on Emperor, where the AI gets several bonuses so will have larger, more advanced armies nearly all the time, and will not be turtling.
However, I have turtled several times. By turtle I mean inciting enemy attacks where they waste their energy and I win by attrition. Obviously this works better in multiplayer. And works best on maps with chokepoints.
Also, seals victory condition (Golden Realms expansion), where you capture and hold a seal until the timer ticks down, is almost by definition a turtle victory. Just be aware the AI is pretty good at that too.
So too are Unity beacons. Build those, defend, win.
