For those of you who play chess(it's not for nerds like you think), or at least for those of you who play chess well, you know there is a Beginning Game, Middle Game, and Ending Game. All of these are crucial to win the battle.
Beginning:
The beginning is mainly focused on getting your pieces into good position, setting up attacks around the board, etc.
Stick Empires is similar to this. Buy the units you want and set them up around the map. Also similar, capturing the middle is important in the game as it is in chess.
Middle:
The middle in chess is about capturing your opponent's pieces, trying to gain extra pieces and making strategic moves (forks, checks, etc.).
In SE, we try to kill, because we're not as kind as chess players, the opponent's units. You're trying to limit him/her by killing his/her units. Also, you're setting up for the End Game, buying the units for this section.
End:
In chess, the main goal of the end game is getting your pawns to the other side of the board and checkmating your opponent. Exchanging your pawns for a queen is kind of like buying GIANTS. Buy Giants. The huge attacking units are necessary for the end game. Of course, you can sneak some Spearton in there as well, but Giants should be your key players. I guess you could call it spamming Giants.
Many of you are STILL complaining about Giant Spammers. If you're really so annoyed that you can't find a better strategy, then you should spam Giants as well. Simple as that. If you truly believe it's the best strategy, then use it! Do you think Native Americans would have survived if they insisted on using clubs against guns? Well, maybe they did but if they had built guns to fight they might have won. Do you think people kept using swords when the gun was invented? No! If you think spamming Giants is the best strategy then USE IT.
But for those of you who are intent on finding a defeat for this...
I won't tell you what the strategy is, but the best way is to use it yourself. But wait, I'm not done yet. If you use it yourself, do you think you're going to win every single game? Eventually you WILL be defeated. Then you can use the strategy that defeated your Giants against another Giant spammer. This is the way to find a solution.
Have a nice day :D
