In Might & Magic Heroes VI there are certain treasure chests that let you choose between gold and experience. To beat the game most easily which one should you choose early on?
Generally speaking, a larger army is better than a few levels on a hero, so that would indicate that it is better to take the gold. However, as your hero gains levels, it takes more and more experience to gain a level, which makes the experience in the treasure chests worth relatively less, which indicates that you should take the experience to maximize its effectiveness.
Therefore, I usually choose gold on a small / medium map (when I know I will encounter enemy heroes in a short timeframe) and experience on larger maps (when I know I will have time to explore and build out my main town prior to encountering the enemy).
In the late game, you usually have more than enough gold and a high level hero, which is when I start leaving the treasure chests so that secondary heroes can get a few easy levels.
Because your hero carries over from one campaign level to the next, and because I've never been limited by gold at least so far, I've always been taking experience in the campaign. If you need a boost of gold to accomplish some goal, then by all means take it, but I would only give up the potential experience if you're going to put the gold to an immediate use. It takes a lot of experience to level up as you get further in the game, and one extra level up can mean a very powerful new skill.
Depends on situation. Early on in a map you probably want to take the gold, to level up your town faster, but if you already have enough gold to do that properly, then go for experience.
If you play the campaign, you will probably hit the exp cap if you fight most neutral monsters you can find, and if you have a big set of well developed towns chances are you wont afford all creatures.
There is no easy answer, but simplified; if you need gold take it, otherwise go for the exp.
