Loscaron: I have to disagree. I played both games extensively in the past and I had a hard time to get used to Cap 2. Im many ways Cap 2 is inferior to Cap 1(plus). For instance the interface is better structured in Cap1. The campaign, and the game in general, is more challenging as well (Cap1). The A.I. seems to be better in Cap1. The way you have to "switch" between different cities in Cap2 is tiresome - I liked the one big map in Cap1 better. I also liked the scenario in Cap1 plus, in which you start in ~1950 and you have to research every product you want to sell.
One BIG plus (and why I have only played Cap2 in recent years) is the very decent multiplayer part (LAN, and maybe even online - never tested that). The new concept in Cap2 to build a different store for each product category is also a nice touch.
So when you're looking for a more accessible game to play with some friends: Cap2
If you you want to "learn" a bit about capitalism Cap1 (plus) would be the better choice.
Everything you write speaks to the need for a bundle from the opposite perspective, sine it sounds that you would likely not pay $10.00 for Cap 2.
I think both 1 & 2 should have been together for $10.00.
