I'd say yes.
-Core mechanics very similar to Panzer General 2
-Non-linear campaign via strat map
-Pretty. Units look good and blow up better
- Planes can be used as airstrikes or placed on map as air cover
-Destruction on game maps is persistent! Trash L.A. and it'll stay that way
-Different terrain defense bonus based on unit type (infantry gets +3 defense for cities while vehicles might get -1)
-Late game access to nukes
-I personally loved the modern US civil war setting
-Game maps can be played as stand alone scenarios.
-Faction specific special abilities can be used every so many turns (a la Advance Wars). Ususally you'll have access to 3 featuring buffs, curses, and healing. (Ex. a defensive stance will give you +6 def and -3 moves, lasts 3 turns and can be used every 5 turns(not the exact game specs, but you get the idea))
-Units you produce go to a global pool. When attacking you pick your army from this pool. You can attack 1 territory per turn. When you are attacked, defenders must be drawn from you pool as well (plus a few free partisan units) and your attackers are not available. This forces you to strike a pretty carefull ballance. Sometimes (especially early game) its better to use a small strike force in a probing attack, do some damage, and abort the scenario to return in force later. In fact, the difference in difficulty levels is how many AIs can attack you per turn (easy=1;med=3;hard=no limit)
-System hog (but scaleable)
-Feels generic. The only faction that plays different is the European Peackeeping forces
-No unit experience (but unit damage persistant)
-IIRC, no PBEM
-AI is only meh
-Economy is too harsh. Never enough money and once you start losing, you tend to keep losing. This forces you to give up and go home sometimes instead of good 'ol tank krumpin'.
At $20 its impossible to go wrong so long as you're looking for a good PGII clone.
