The microtransactions are one issue among many. To be frank, putting microtransactions in a $70 USD title would still warrant negative reviews in and of itself, but the the game is also having catastrophic performance issues and crashing on PC for what seems to be the majority of players, to the point of many Youtube channels covering it that did not get press copies being all but unable to play at all.
It doesn’t matter if a game has a lot of good elements, if it has bad ones and people cite those bad elements in negative reviews it’s not review bombing, it’s consumers giving an honest review of a product.
For reference, $30,000.00 in 1966 would equate to over ~$285,000.00 in 2024’s USD.
