Well I do not like C&C (but I own the older Vive L'Empereur by GioGames that is quite similar... I did the English translation back in time, anyway the art is nice and the game works) but at least Borg has a following and C&C is quite light. In the box you have also different armies and you can do quite a lot of different battles in Both Case (VlE was out before C&C and it is quite close for a lot of things, but I think it has a better graphic approach). Probably Lance McMillan "Fading Glory" (still from GMT, but the battles are available separately from VPG games) it is meatier. I have the Jena teaser game they included in C3I (their own magazine) and sooner or later maybe I can be willing to try. Professor Sabin was quite critical of it... but well I am not 100% in agreement with Phil for a lot of gaming things. I am usually for more complex games.
Jours de Gloire is quite interesting. I have all the VV games, the origianl Triumph and Glory by Richard Berg, and some of the stand alone games published later (need to get Berezina and Montmirail as soon I have money...) They do not use cards, but chit activation (and you need to decide which Corps/Division you place in the cup based on your command points...). The combat is based more on quality than numbers (but still numbers have a role) and has a single D10 resolution. I think it is quite easy to get in and very rewarding. A couple of years ago I used one of the smaller battles with a student in KCL (consim class). She was able to play without too much problem after reading the rules.
All the best,
Arrigo
