I just finished a game with Austria on King difficulty, Standard size and speed. I went Tradition>Statecraft>Imperialism>Freedom.
Regarding their UU, Landwehr, it feels a bit underwhelming. Since this unit comes quite late (Industrial era), their kit seems rather weak. The Regimentsmarsch gives such an insignificant amount of
Culture that I wonder why we even bother. If they give a bit more
Culture when garrisoned in cities and that extra
Culture is added to the pool of the city, then I can see it having a bit more impactful with all the modifiers. Otherwise, this promotion seems useless at this point of the game (I had about 600
Culture/Turn when I unlock the Landwehr and not in a GA). The other promotion, Imperial Vigilance, seems to have less impact with its +25%
CS. At this stage of the game, you will hopefully have other sources of bonuses that diminishes the extra
CS from this promotion. In addition, the Landwehr has 3 more
CS than a Fusilier which doesn't help the Landwehr deal with one of its biggest threats of this time, Gatling Gun. I know Landwehr is designed for defensive wars but, when on the offensive, it's really not that much better than the Fusilier it replaces.
Then, we have the UB, Schützenstand, that have a kit that doesn't work smoothly in my opinion. The
Production and
Culture, both yields and those from CS, are really solid. It's the +15%
Production towards Land Military Units, +15 XP to Gunpowder Units on Training and +30%
to Gunpowder Units that's in an odd spot. Now, this UB gives the same amount of supply as Arsenal from
Population. In my game, I built this in all my cities (7 owned in total) and I have about 30 military supply. If I had went for Authority, I would have quite a bit more. The UB allowed me to reach my supply cap quite quickly and then a good portion of the kit is then rendered useless. Ideally, I don't lose units so I won't need to replace those lost units. In addition, the UB becomes less relevant once I went Freedom as buying units with full experience is far more useful than building a Gunpowder unit from scratch. Overall, I find it weird when I can build units faster but supply cap is the biggest issue, especially when the UB replaces the Arsenal). I feel making the UB give +25%
Military Supply Cap from
Population helps their kit more. If that's a bit much, remove the +15%
Production towards Land Military Units so the Landwehr (hopefully after a small buff) gets to shine more.
Anyways, these are my thoughts on Austria. I don't mind hearing opinions of others about this civ.
