It’s not “wrong” per-sé, but in the context of the sentence, it just looks a bit wrong.
It is the text you get when your employee wants to get the security upped:-
“Hi Boss! I have a knack for security and I think we could really do with some security upgrades in our office.
I have done some research and I think with an investment of (Money amount) we would be a lot safer than we’re now.
What do you say?”
IMO it would be nicer if it was “we would be a lot safer than we are now.”
A small typo also
“Our fan base is big enough to make self-publishing large games viable. Unless a publishing deal gives us a great royalty rate we are likely better off publishing large game ourselves”
I think that was meant to be “large games”, alternatively you could put “better off publishing a large game ourselves”, that would make sense with the context of a single royalty rate.
but we’re is incorrect English in this instance (just checked with my wife who’s a writer), if you say it out loud “we’d be a lot safer than we’re now” (because you would prenounce it like weird without the d) it sounds incorrect, where actually saying “we are” sounds much better English.
That’s what I meant, that’s why I said it wasn’t wrong per-sé, the word we’re means “we are” which is right, but how it is said and the use of it in that context doesn’t flow correctly, which is why “we are” would be better.
