Re: Does Hero System "break" at higher levels, and if so, at what level?
I think many problems encountered by people on this thread is not so much due to "system breaking" but more to how the system was used.
Hero is a toolkit providing a lot of flexibility, power and freedom and as they say, "With great powers come great responsability". To make a game ork at *any* level, there is a minimum of control required. Of course the less point you have to spend to less abuses and balance issues arise but still, you have to adhere to a certain way of doing things, This "way" varies with genre, starting points, groups, etc.
For example, our first Hero games, many years ago, was built on 375 points. Excited by the freedom provided by the system, every players decided to create the hero he wanted and the gm was quite happy to let us do our thing. The result was less than sterling. At 375 points, our group was totally unbalanced. While a martial artist could bring down Viper's mecha with a few power kicks, the powered armor could not even hit one. Hero was not at fault here, we were. We just didn't know how to use that amount of freedom.
Now, after many campaigns at different game level, I can say that we didn't suffer such imbalance in a long time. We have played games starting at 75 points and others at 1500 points and everything went quite smoothly. Sure, there is always a player succeeding to have more bang for his money but never in an outrageous way anymore.
We curently play in a 600 points campaign and I must say it is one of our most enjoyable so far. Characters are well balanced, everybody has his tricks but nobody is a one trick monkey either.
It all comes to controlling the freedom given to us and using it intelligently.
Now to answer the initial question. "Does the system break at high level?" I would instinctively answer "Yes" just because everything tends to break at some point. I suspect this limit must be quite high (significantly higher than 1500 points) but have no clue were exactly. Hero is one of the most flexible, scalable system I know of and I have never reached that limit.
If the question would be "Can we break the system?", I would wholeheartedly answer "Yes, you can do it at any level! I know, by our own faults we did it at 375 points"...
