One thing that fell a little short for me is the hidden scoring conditions. Before my first couple plays, I was really excited about this concept. I really liked acquired marks so that I could get information about final scoring that my opponents didn't have and give me a direction to go in. The problem I have with this part of the game is two fold. First, there are 12 consortium votes available each round - but it was very rare in any of my playthroughs to see any players who had not placed out all or nearly all of their marks. The problem is that there are so many voters available that the variation of which voters are available each game is not very big. For the most part, players will want to try to get the most of everything, and need to find the consortium voters who are looking for specific color spells and supporters. I guess since my expectations for this mechanism were so high, I got to be a little let down after the fifth time I marked the "most gold" voter - not super exciting.
Another thing that I didn't love about Argent is the feeling that, even though the game adds a lot of really interesting twists to the worker placement genre, at its core, Argent's basic gameplay of "place a wizard, get resources," is still pretty stock worker placement. The different wizard's special powers didn't come into play nearly as often as I would have liked, and their abilities are not super exciting anyway.
Although those two factors didn't hit for me, I did have a great time playing Argent. The theme is great, and the twists the gameplay does offer are fun to play around with.
