Balance issue: I've given this a bit of time to think over while I've played the game to test it more, and I've come to the conclusion that unit-boosting buildings (such as Barracks, Armory, Stable, and Forge) are heavily overpriced and almost useless in all but the most select situations in Civ5. The whole point of having an option to build a Barracks/Stable/Forge (etc) in previous versions of the game was that it's supposed to be an investment that pays off in the long term. This worked fine in those versions of the game (Civ4 in particular), because the amount of units that you build per city in the game is enough to make the buildings eventually worthwhile in at least a handful of unit-producing cities. However, the same concept doesn't work when you transfer it to Civ5, because the number of units you need to (or are able to) construct is far, far less. I've come to the conclusion that in the present state, it is actually NEVER worth building a Barracks/Armory/Stable/Forge almost all of the time in Civ5, except for perhaps occasionally in one single city towards the mid-late game. Those buildings just aren't worth their cost. Also, the problem is compounded by the fact that units rarely die in Civ5. This means that having a greater number of non-promoted units (rather than a smaller number of units with a promotion or two) is even more important. For instance, would I rather build 3 Swordsmen in a city, or 2 Swordsmen and a Barracks? The 3 Swordsmen of course. Would I rather build 5 Horsemen, or 3 Horsemen and a Barracks + Stable? Don't be silly. Would I rather build 5 Knights in a city, or 4 Knights and a Forge? You're kidding, right. I've noticed that many other buildings aren't worth their cost/maintenance either. Basically one of a few things needs to happen. Either: 1 - Reduce the cost of these buildings so that they're actually worth constructing some of the time (for instance, halve the cost of Barracks/Stable/Armory). 2 - Increase the benefits of these buildings so that they're worth constructing (for instance, the Forge should give a 30-50% boost on units, not a measly 15%). 3 - Increase the cost of units relative to buildings to achieve the same effect... this I would definitely not be in favour of, as units are already too expensive for the most part in my opinion. 4 - Increase the hammer output of all terrain. Seriously, it's pathetic at the moment in Civ5. I have to aim to get Golden Ages as often as possible just to compensate for the abysmal hammer output, and even then it isn't quite enough. Anyway, just a few thoughts.
