so instead of explaining the theory you just decided to insult me? Thanks. And no, I've never done facebook games.
I've explained the core part of it in my post and left the rest for anyone interested enough to know the details. Making facebook games is not a bad thing, albeit different it requires a set of skills, if you are that offended I can happily offer my sincere apologies.
I'm sure FTB also decided to add GT into their modpacks not other way around. Modding already is a derivative work and modifies the original game made by Mojang, getting pissed at someone modifying how your mod acts is really weird. GT has really good config options and you can modify it to your will.
GTech actually works better in 1.5.2 than it did in 1.4.7. Alot of the mod authors have started to implement GT recipes for their mods. GT does make the game harder, it forces you to use tools that you otherwise wouldnt. You can't just rush to get a quarry or rush to solar power.
There are lots of good things GT is doing but also there's lots of things that i disagree with.
It would be just speculation so I will just state one fact and let people to make assumptions, core of FTB plays on Forgecraft servers, there are two Forgecraft servers with third using Terra Firma Craft is coming, none of them uses GTech. In case of argument that Forgecraft is for bug testings, only Forgecraft 2 has this as it's main purpose and there is Forgecraft 3 with Terra Firma Craft.
I can safely disagree with you on the subject of config options, a good config option can be found in both Thermal Expansion and Forestry, especially forestry has a global "difficulty" settings. I have tried GTech on 1.4.7 and earlier versions, I may give it another chance in summer to see if it really changed the way it behaves. Again, GTech does not make the game harder, mining five minutes more is does not mean hard or waiting 10 minutes for a machine to complete it's job is not hard, it is just more grind.
I am not saying that GTech does not have it's positive parts, the idea behind industrial centrifuge and industrial electrolyzer is great though their implementation is total failure. Fission reactor is also a good idea, industrial grinder is also a good idea yet it's implementation is also a failure, if you have that much resource in your hands you do not require to use an industrial grinder. Since you are a game designer, I can give a different example; GTech is a game where beating an optional miniboss encountered in early game requires lets say Oblivinium Sword of Miniboss Slayer yet in order to craft it you need to beat one of the final bosses then what is the need for such a sword? It becomes pointless and collecting other ingredients which require ten times more time than required to beat the game itself makes that sword totally useless.
If GTech was not an add-on to IC2 and a mod to Minecraft and a mod not compatable with other mods like Terra Firma, I can say mechanics might change and it might turn into an acceptable mod.
And people are still saying, GTech does not introduce grind to the game, please disable GTech and play once with it disabled.
