Reus is like Terraria, if Terraria were about running between crafting stations to craft item after item before the egg timer at each station went off. You must meet randomly selected development goals by putting plant, animal, and mineral resource tiles in the right symbiotic combinations within a time limit. This requires memorization and some luck. Development goals are tied to individual villages. Each village has a rigid tile range. This range grows but, to meet all but the most basic goals, you must upgrade tiles. You get a preview of available upgrades for a given resource tile. What you CANNOT get in game AFAIK is information about which sympathetic tiles an upgrade requires. You only care about the attributes of a tile. So while the game is telling you that your frog tile may become an iguana tile that gives more wealth, what you /really/ need to know is that an iguana tile really only gives more wealth when it's next to a mineral tile. This is a problem for you since you've already surrounded your frog tile with the Elderberry plant tiles that it prefers, and your rock titan is on the other side of the planet at the moment. The game does link to a game wiki, so I guess you can tile your windows. There are other aspects to the game, but this review is too long.
