Considering we all knew that Sony Studio games were going to be £70 at launch since the PS5 was announced, it seems mad people are still going on about it now.
If you're buying physical then it's unlikely you're paying £70 at launch - many people happily buy at launch, complete the game, get most of their money back from reselling and then buy again (to keep) once it's cheaper (if at all).
Nobody should be paying £70 at launch for the digital version either, with buying Wallet Top-ups for lower than the face value, it should be closer to the £60 mark.
If £70 games are too much to stomach then stick to buying games 6 months later when they have taken their first discounts, or keep an eye on the likes of Ebay from around 3-4 months after release and pick up second hand.
I buy very few games at release unless I can get a large discount, although Forbidden West may well be one I do.
