Well, for one if you don't have a spellcaster capable of negating an invisible opponent's advantage, then you can go out and get a lantern of revealing or somesuch other magic item in a normal D&D campaign so that you can deal with those issues if need be. In a low magic world, that might not be an option, and you are left either with someone playing a class they don't want to or just running if you are up against a wizard that can cast [greater] invisibility.
A few points:
One reason I am seriously in favor of lower-magic games (hopefully you've read this entire thread to know in what context I have placed this concept) is the agonizingly lame "Magik-Item-Quickie-Stop," where "adventurers" may stroll on down to some Ye Olde Shoppe and just sort through magical trinkets at their leisure. In a setting where individuals with enough wealth to even benefit from such a place are such a tiny minority, how or why would businesses survive when that minority is so obviously their only clientele? Additionally, all those items came from somewhere: spellcasters who created them in the first place. Judging by how it is supposedly so "easy" to gain said items, there must have been hordes of wizards, clerics, and others sitting around devoting lives to crafting items. Where did they all go? How did they all get so powerful (how could there me ANY monsters or threats left in the world?)? Did Elminster bring the concept of Mass Production to the fantasy worlds from his vacation spot in Detroit?
However, if a PC uses his feat to make his own items to do whatever he wants to do (including making them for others in his party to use), I would never dream of placing any restrictions on that...and would find it to be completely lame for DMs to do things that artificially hinder said activity.
As for the continued Greater Invisibility panic: We are talking about at least a CR 7 encounter (4th level spell; 7th level wizard). Even assuming there is not a single spellcaster in the party (rare, but I have been there), I would expect characters (especially those who have gotten that far) to be able to use their heads. Run, hide, wait for the spell to fade, throw flour up into the air and all around them....the list goes on and on. Maybe everyone should get out their bows and ready themselves to shoot at any sound in the room (unless the sadistic DM really is TRYING to kill the party by saying "Coincidentally" the wizard has prepared a crapload of Silent Spells). It is not extremely likely, but that is why it is called a CHALLENGE. Heck, many offensive spells have some sort of visual effect that will show the point of origin, allowing characters to blast away with bows and blows.
If all else fails, the smart adventurers - the ones still alive at the end of the day - know that sometimes you just have to run; the upside is the fact that you have learned more about your opponent. Brains will beat magic item dependancy every day of the week.
I recognize that we have our own styles. Whoever said "I like more magic items and higher power games," is perfectly cool in my book. Choices and likes/dislikes is what makes life interesting. Those that claim the low-magic game "cannot work" or is "the result of incompetence" should not be throwing stones from behind your glass sheilds.
