1. Bionic Granny.
I wasted 50p getting this from a bootsale thinking it would be a laugh. It's not, it's a terrible, terrible game, a bad idea, and worse execution.
2. Ikari Warriors
At the other end this was my first regret purchase back as a kid. NES games weren't cheap here so you read every review to see if you weren't disappointed. This shares so much with the above game. Mainly being slow and bastard hard and cheap. Wasted £30 back in the day if you must know and taught me to always read the review.
3. Rainbow Islands NES (USA version)
Always wanted this on import back in the day but my dad always stopped me, then reading in Total
, that Ocean were doing a port, decided to wait. Found out much later that they hated the American version and decided to do their own. And playing it can see why, its not as bad as the two above games. Its just a middling port, its just that every format has its own, much better version,than this.
4. Bubble Bobble Evolution (PSP)
Do you wish Bubble Bobble was remade as a pseudo 3d platform puzzle game where every element is ineptly done including your heroes cosplaying as the main heroes.
5. Elite (Various)
I tried to love this space trading game, and though its a technical marvel, it's just too hard and unfair. Its follow up Frontier has issues but I absolutely loved. This has never clicked on any platform I've played it on.
