Hmm, this is a long list

And this is only the stuff I got. Although not all are actual 'wargames' many of these fall under this category in one way or another. They all are games in one way or another.
Also note that I used all the "English" names for the different games although most games I have are the "Dutch" versions but for easy reference for the members here I thought it would be best to use the English names.

As for more Wargames, I found a shop here in Rotterdam that sells AT-43, Confrontation and Warmachine/Hordes so they have quite a big range. Also they sell GW stuff at a discount I've heard (but are not really sure about that)
I'm not really a fan of this AT-43. For €80 you get a box with 'only' 17 miniatures in it, a shortend version of the rules (like the ones in the boxes GW makes) and a few bits of scenery. Although the minis are painted they are not too good. Only a basic layer and then an ink over it. Which is a real shame considering how much money it costs. The scenery package is quite interesting though.
I also found out that this Confrontation starter is of really good value. For €50 you get 9 models (although all metal) it's a freaking heavy book and it looks like they got the complete rules in that set. But I'll have to ask there or maybe you know Hunter.
