I have noticed that there are few comments about the new way in which depleted units get replenished introduced in Napoleon TW. I think that this system is absolutely the best compared to the previous seen in the series and I am curious to know if other people agree.
I remember the first system in Shogun to retrain units: it was awful, it involved drag-and-dropping units cards around in the city screen... I never used it, it was far simpler to just merge together depleted units.
In Rome and M2 the thing was somewhat easier to manage, you could refill units in the same screen used the train new ones but it had a couple of drawbacks: 1) you could only retrain units inside a city 2) you could only retrain units which that city was able to produce (so it was a pain to retrain elite units recruitable only in core regions).
Empire was a great improvement: you could now retrain your units everywhere without limits; anyway that very improvement made it felt a bit "weird" because in just 2 turns you could completely retrain your best unit types in the most forgotten places of the world.
Now in Napoleon we get the best of both worlds: we can retrain units anywhere AND the most common units retrain faster than the elite or regional troops. PLUS we have the added benefit that retraining is automatic and doesn't need micro-management any more!
What more can we ask? I never really liked the previous systems but now I am satisfied. What do you think?
