Quoted from Jediturtle:There are many ways you could go with this, but for me it always should boil down to variety. How you get that variety is the question. I agree with your idea of pairing a fast/flow game with a stop-go/shooters game.
Do you want to stick to the same era?
X-Men + WOZ
spiderman + RBION (some would rather say FG)
ST:TNG + TZ
CSI + 24
High Speed + Pinbot
BK2K + FH
Black Knight + Blackout
Or how about a huge contrast...
Cow Poke (or any EM really) + Attack from Mars (or any fast playing DMD)
If I could pick just one pairing, it would probably be ST:TNG + TZ. So much the same, yet so very different.
I love having many eras, designers, and play styles represented in my collection. Variety is the key!
I agree on TZ and STTNG. You basically have the ultimate, loaded up, money is no object Pat Lawlor stop and go game against the ultimate maxed out Steve Ritchie flow game. Probably the two most innovative and feature packed games from the 90's.
