Let's look at the options. First off... Ratchet:

Problem - Guns. Not exactly something all perants would aprove of.

Next we have Kratos.... on second thought.... there's no point. I'm sure you've seen the dude lately.

Next up, Jak. The first jak would have worked just fine... but how's Jak now???

Uhhh.... he has a few inner emotion issues that he needs to work out b4 we can start talking mascot material...

Next up :- Sly Cooper!!

Wait.... the dude's a theif right??? Well.... that ruined his chances.....

Ok... now we take a look at Sackboy

It's pictures like this that just melt your heart away....

Who could say "No" to this little guy??

But just look How cute he is.

Can we really see enough Sackboy?????

I kid, I kid!

We could never see enough of Sackboy. Never.

I've seen quite enough of Sackboy, thank you very much. However, a lot of that is because I don't find the character cute as much as creepy. Either way - Overexposed... Not yet. But they're really heading that way. Haven't seen a character get whored out this much after only one game since Dante. But the Dante-stuff cooled down a bit, maybe this will too?

Well, there is certainly less sackboy than there were stuff about killzone 2, which was getting annoying already. So the answer is no theres no too much sackboy.

It been brought up before in the thread already, but what there is to much of is Mario. Mario Tennis, Mario Kart, Mario Golf, smash bro brawl etc. etc.

Also you can add Master Chief to the "to much" list.

Hey, if a middle-aged Italian plumber from Long Island can be found cute for kids, a Sackboy can as well...
