I bought It Takes Two through Steam a while ago but only got around to installing it recently. I now realise it uses EA's launcher which is a big piece of shit. Add is some issues linking my EA account to my Steam account and I'm done with it.
It's been a while since I pirated any games, it used to just involve a key gen or copying a few modified files into the right directories.
These days I see whole 'repacks' from fit girls and skid rows.
Is there anything I can do with the game I've already downloaded or do I need to download a repack from someone?
Well, you'd need to find a crack separate from a repack because they aren't in a format that lets you grab the data you need.
Also worth considering that your crack needs to match the game version in most cases. Updates to binary files are likely to make older crack versions incompatible. I tend to just download the repack and add the repack exe to Steam to make everything integrate well and to avoid automatic updates breaking the game.
