If you're trying to estimate sales performance without any actual data, then yes, a fair comparison is of the utmost importance.
It reminds me of a poll I saw gauging the number of people in each age range that owned a particular car. Everyone was shocked that the 45+ age range (no cap) had the highest ownership levels, despite the fact that all other age ranges were in 10 year increments. They tried to come up with all of these asinine explanations that didn't matter.
Flawed comparisons tell you nothing.
Not sure what you're on about there.
Lower numbers are lower numbers, insert your reasons here it doesn't matter. I gave some data and already explained it's just the launch compared to recent titles. Who knows how it's selling elsewhere or how well it will pick up I already said I feel it will.
I'm certainly not in the camp that it's bombed or failing, just giving some data about the UK launch and a possible reason some are noticng less players, a fair comparison doesn't come into it. Someone posted a link that its selling well because it's 2nd in the UK, I gave some actual data as second place in a chart whether its games music whatever doesn't mean it's selling well.
Anyway, even it drops off in sales a bit or takes a while to get going, it's still an important game, a great pack in. I doubt it's in trouble.
Another point is while we're missing around 50k of UK people at launch to previous titles, mainland Europe is a lot of ground lost for XBO so Forza 6 players might be missing some French, Spanish, German and Italian fans who are yet to buy the console.
Finally, if Horizon has had an effect, they still sell a large amount of games each year when you add it up over 5 years.
