Ergggo, I have been doing a similar thing with a good friend of mine for many years. I moved to a different city in a different part
of germany so we could not meet up anymore on a regular basis, so we switched to connecting via skype. Difference is that
we don't share the same pc , each of us plays the same game on his own pc and during playing, we talk about the game, without
spoiling puzzles. It is much more fun to share the gaming experience rather than playing alone. To not give hints our conversation goes like
this, for example 'Did you already find the item starting with 'bro'? (maybe 'broom'). If the other person says yes, we know he also
solved the puzzle to get the broom and we can openly talk about that puzzle.
Sometimes, we cannot resist the temptation to tease the other a bit ('Did you still not open the doort with the 4-color code?')
This may all sound a bit nerdy, but we enjoy it very much. I certainly prefer it to playing alone,
