Yeah, driving away part of the potential fanbase on word of mouth alone. In this regard, the app could be without major issues and could enhance the gaming experience to some extent, but yet you could have a vocal enough contingent of users hellbent against using the software because they simply do not like it or the company that created it.
Honestly, I have to wonder how many of you complaining about GFWL have actually used it or experienced the problems you claim exist and are merely passing on what you have heard from others making these claims.
I honestly do not know enough about GFWL do judge whether I should or should not purchase a GFWL game, but if all I hear is negative stuff, then no, I most likely will not buy the game, even though the game may in fact not suffer form the GFWL software. So, yeah, in that regard, I could be passing up a great game just because I listened to some dude on the internet.
Oh no doubt, but this also goes both ways.
I know from my own personal experience that GFWL doesn't absolutely ruin a game, I will more then likely buy a game that has it if the game itself is good. With that said GFWL is really garbage in my mind set, and I would totally enjoy the games I play that have it more if they were without it.
I can recall several times where I've been able to connect to steam, and the internet on Dawn of War 2, but not been able to connect to windows live. On top of that my friends list is full on windows live, yea full, what kind of system says you can have too many friends! There is also no instant chat function, in order to communicate with anyone on windows live you must send private messages back and forth as if you were sending private messages on a forum. Sure you can communicate with a private chat session for microphones, but not everyone has one or use one, and why would they support more options for voice over text? This makes sense for the 360 of course but not alot of sense for PC.
Lastly windows live is slow, I'm sorry but it really is, there is no doubt, I've never seen a system as slow as this. It takes forever to download profiles and updates, the interface itself is even slow, animating its way from your friends list to your achievements, this should merely take a second or less to do but because it must look pretty in the process, it takes much longer.
In the end, yea sure I'll go through it's pain to buy a good game, but I cant say I'd enjoy having it there. However this much is true, the game would be a much better experience without it.
