So, the Game Boy Color comes in at #1 with 8 games, with the PS3 coming in at a close second with 7. However, what is interesting to note is that the Atari Lynx had more 10s than the PS1, PS2, GC, XB, N64 and PC combined. Go Lynx, I guess? What are your thoughts?

No PS2, PS1, or Xbox games? That's strange I thought they would've given at least a few of those system's games a 10. Halo and Metal Gear Solid come to mind but there are undoubtedly more. Of course that is my opinion and not IGN's but is there any chance you missed a few?

*edit* I see they have the MGS Gameboy Color version rated as a 10

I got the list from Wikipedia and confirmed that they did indeed give those games a 10 out of 10, except for Halo: Reach which only IGN UK gave a 10 (I did not include it on the list). Wikipedia may have missed a few, but as far as I know they did not give any PS1, PS2 or XB games a 10.

Yea I double checked and in fact there are no 10/10 games on those systems. San Andreas got a 9.9 and there were plenty of 9.8s and 9.7s but no 10s! TIL

That's why I'm surprised about the Lynx. How could the PS1, PS2, N64, GC, XB and PC combined get less than it?

Surprising yes but it could be because of the fact that IGN reviewers only review games for one system. It could be that the Lynx's reviewer was a lot more forgiving with ratings compared to the other employees. It's hard for some people to objectively give out a 10, because a 10 means that a game should theoretically be perfect. Not everyone has that mentality though.

On a different note it would be interesting to see Gamespot's and Famitsu's perfect scores as well if you ever get a chance to update this thread

Does Mario Golf on GBC really deserve a 10 out of 10?

Gamespot and IGN gave no 10's to 360 exclusives? You learn something new everyday.

Have they really given out that many? Back in the "Golden Age" of JRPGS I can't recall there being that many 40/40s from them. Maybe their standards dropped

@VGPolyglot: Thanks man I kind of figured GameSpot would not have that many
