The field editor is very basic tbh and could use improvements because almost all the prior games had simple controls for field settings but they all also had "custom" field settings.
I think they can easily add Custom field settings, say 10 of them and you can pre-set them and choose from those.
Also, the pre-chosen fields are sometimes very poor and I sometimes don't find the field setting I want from the presets. Changing to what I want works for a batsman but then changes for another and I have to do it all over again, each time a new batsman comes to the crease which is very annoying.
Still, you can change the fields and it does work.
For vers 1, I would say they have done a fair job and if DBC15 improves this aspect, that would be compelling improvements to warrant further purchases etc.
The Madden Football model here. Make a good base game, then start making incremental upgrades while your fans support the base game and you start growing in install base etc.
Overall, the game is quite promising for a v1 foundation.
