Yep, that's how I've long felt.
As a kid I swallowed all the Bruce Everiss-spun hype that this magical/mythical hardware widget would add groundbreaking new features but it was just a RAM upgrade, wasn't it? And a mere 16K one at that, IIRC. So, in fact, these 'mega-games' were going to have all the power of... a 64K Spectrum.
For that, Imagine were purported to be looking at a retail price of £30. With inflation that'd equate to around £90 today. Who would pay £90 for a game even today, when many titles really *are* mega-games? Sheesh.
