Currently capital cities are placed on the coast most of the time. Because of that a large number of city hexes are in the water which can't be built on. This is a serious handicap and often requires a restart. So, some suggestions to fix this:
1) Allow water versions of the land buildings to be built on water hexes
2) Or, create unique water based structures to build
3) Or, (and this is probably easiest to implement in a patch) add a "land fill" spell that allows you to turn a water hex to a land hex so you can build on it.
Warlock uses bacically the same combat as Ino-Co's previous Fantasy Wars and Elven legacy games, which I liked. What puzzles me is why they did not include the ranged defensive support fire that's in those games. That was also a big part of Fantasy General and Panzer General. It allows for the use of combined arms and provides more tactical depth. I would like to suggest that they think about adding that back in.
There are no heroes at all in Warlock, which is really the biggest departure from other similar games. Even the Fantasy Wars series of games had heroes. A lot of the fun of these types of games for me is recruiting, leveling up and equipping your heroes. No heroes means no equipment. There's no swords of firey wrath or shields of +3 movement in this game to be had via monster lairs or quests. I would like to request that they add heroes and equipment to the game. Being able to get equipment from quests would add a lot of appeal to them.
There's no empire status info screen at all and it is sorely missed. You can't tell who is at war whith whom or which city has which spells cast on it. Please add a screen that displays this information along with your empire's statistics.
There's no score screen or game history stats screen after the game ends. It would add a lot to game replay value to add these.
Multiplayer and selectable victory conditions have been confirmed to be in a future patch so no need to list them.
