Sounds to me like MS needs a very clear split between gamerscores/achievements whatever (I'm not on Live) that pertain to offline SP modes and those that pertain to MP modes.
I can understand gettting a download save to get by certain parts of a game you're stuck at but of course the second you go online you are taking part in games with others and any cheating that affects those other players should be punished.
Mind you, if the only MP cheat is an inflated score I've got to say there are more alarming things (like terrorism and global warming) that are on my minds than that. If I did use Live I wouldn't care too hoots someone did care about their score so much they cheated to make a a gigasqullion... but the second they cheat in a way that affects me (exploits, aimbots, etc) then I want them banned for ever and poked with a pointed stick (repeatedly).
Maybe its just another reason I don't have a 360 but the whole achievements thing just seems... well, kind of silly to me. Sorry, but it just doesn't matter much to me whether I get 5 headshots in a row or have carried a garden gnome from the start of the game to the end...
It's like when I play Warhark - I keep getting awards for stuff and never really notice, nor do I pay any attention to the rank of others. I guess from some its a nice additional sense of achievement - but I'll settle for winning the game myself.
Try to be reasonable... its easier than you think...
