Why do people debate over minecraft vs Roblox?

They are 2 different games but people will go all day saying how and why which one is better.

Can you give us more info?

They are both based on building but that's the only similarity they actually share.

I've never once heard about Roblox or anyone debating about it over Minecraft.

Mostly because they liked to show there bounds and show to the world they care about that specific game and not the other

Because they are both blocky, and they are pretty much the only well known and played games like that.

Because they are board and have to much time in the day.

Because people feel that if more people play this its better or if they played it they feel like they have to be better then people who play those games

Why do people debate over Cod/Boyfriend/Halo/Gears? Human nature I guess.
People need to realize its all about preference.
