Very well said Sky Shadow. The great thing with the old Marvel G1/G2 comics was that we did get individual stories in each issue and a story arc! Take the Matrix Quest for example, each part is a contained story, i.e.:
Part 1: Detective mystery
Part 2: Wild west frontier with vampires!
Part 3: An Autobot's quest for personal vengeance
Part 4: Thriller/horror
Part 5: All out action aboard the Ark as the Matrix completes its journey to the dark side
...yet collectively they all form a single story arc (which had beginnings from issues long before the saga even started! (e.g. Deathbringer)). These issues can be easily read and enjoyed either on their own or all together. For example, you could pick up any of these issues without ever having read a Transformer comic before and still follow the story and enjoy it.

That's something I find sorely lacking in Transformers comics these days.
