I think the only unknown left for most sim folks is the blocked pit stops, rest of the pCARS2 sim stuff seems to be intact based on their claims so far.
Bumping cars and upgrades is equals to Grid now I guess? Even if they indicates it as Grid, how does it even hoodwink sim players into it when no one thinks Grid is a sim.
If a someone trying to hoodwink sim players into an arcade game, they would have made a trailer that is appeal to sim players instead of making one that has a similar feel to a different arcade title like Grid.
I highly doubt sim players will just buy any racing games, the whole sub genre runs like a cult where any bit of extra effect is instantly labeled arcade and thrown off their sim list.
If a single trailer is enough to proof the game is an arcade then what is the point for sim players like you to stick around? Also considering that majority of the sim community treat the pCARS franchise as the least realistic, was it even surprising if they really switch to be more arcade?
