Unlike most future endless runner games that took on this formula, Subway Surfers has stayed as an endless high score runner to this day. Movement feels solid & fluent. Collecting all the characters, costumes, & boards can be fun. You can get a lot of things without having to pay a single dime, yet it does take a while, as you have to play it. Rewarding the player with goodies for putting in effort is also a great move.
