to anyone wanting to make a game.A good game has several characteristics:
1.Human minds are always inventing that why we dominate species,a good game has different visual upgrades.Like in stick war when sword is upgraded the sword looks different.
2.moves,like in tetris`D when u press k u do a flip onto the brick.The movements have to be like in a action movie like if u make a free running game,u need to do table slides or flips and dives all that.
3.genre.Right now if u make a sports stick game it will not be popular.Right now the best things to make are fast action and fantasy.
lastly 4.Stress.If u make the hardest game in the world then people will start breaking computers.If it is too easy than people will win it and forget it,so u have to have a fun game at first but WAY later on it gets kind of hard.
