I came to the conclusion that 4E actually had more to offer on the strategic level. The biggest decisions were made when building a character...and, although this usually got lost due to individual player preferences, assembling a party. This made me suspect that despite all the claims of influence by MMOs, it was possibly (and probably ultimately to it's detriment) influenced more by miniatures gaming.
That's where there'd be a lot of room for a computer game. Exactly what defender would work best for this party?
I did think that on the individual tactical level it didn't really go that deep, I played a lot of different characters at one stage, and found you could usually quickly come up with a standard approach to most situations that worked in 90% of situations. (That's why I played a lot of different characters - if I wanted to explore possibilities there was much more to be done in the character generation strategic level.)
