I also disagree. There's a couple years on the list where the top 10 didn't even make my list. The best game in say for example... 2011, might not even be one of the 50 best games of the decade. It might have just been a shitty year. Decade is a completely different perspective.
I mean, yeah, some of he big obvious ones are at the top of my list. But my list is not mostly top 3's. By my count, 11 out of the 20 games on my list fell outside the top three for their respective years.
Only one of my top 20 is in the top 3 of any year, that said, I still stand by my prediction, though I might stretch it to games at or below 5..
Time will tell. Let's see if any game below number 5 in its respective year actually ends up in the final list.
