9. eFootball PES 2021
Only Konami could take one of the only remotely reputable parts of their entire company - Pro Evolution Soccer - and find a way to screw that into the dirt as well.
Enter eFootball PES 2021, a rebranding and almost soft-reboot for the multi-decade old IP, that Konami would then boot out the door in a state that I'm not sure legally qualifies as a digital product.
Aiming to be a free-to-play alternative to the premium, increasingly over-monetised FIFA, the glitches and bugs were immediate, footballers' character models an instantly meme'd abomination, and everything about eFootball feeling like a worthwhile platform for content to be plugged in simply didn't materialise.
Konami would immediately apologise for everything I guarantee developers were screaming at them needed fixing in the first place, and eFootball has stood, barely-upright, ever since.
