Rather than critique the many installments since, the folks at Classic Game Room have opted to review Black Isle Studios' original Fallout. There's no overall score, but they clearly find it a worthy spiritual successor to Wasteland:
Fallout may be over a decade old now, but it still holds up as an immersive and original RPG today. Some ideas do feel like a proof of concept with a lack of thorough execution, but perhaps this opinion comes from the fact that newer games offer even greater depth. Regardless, Fallout is still packed with some great moments and enough variety to provide plenty of replay value. It has the love and support from a dedicated fan-base for a reason, because there's no other series quite like Fallout.
