The user interface does not make an easy to understand game, easy to understand for me. I played two or three battles before I realized why I had a genestealer squad in the first place.
Plus there are icons on the upper right corner of the screen that look like they should be accessible. I haven't figured how yet. I'm sure I will eventually.
Slightly concerned about online matches. The Marines will have to be ready to counter not only enemy movement on the board but also opponent card playing. Meanwhile the genestealer isn't pulling random blips anymore. That definitely changes the game.
I suspect like the board game the online matches will suffer from not being able to have fun even when you know you're going to lose. I think few suffer the frustration to experience losing in order to learn and will move on immediately. A shame really. Then again I'm cynical, not a professional and have no supporting evidence for my position.
