Darvond: Okay, but of 38,000 flash games, just how many of those are actually worth playing?
Here are a few that left a lasting impression on me so I still remember their names after several years:
* Ball Revamped: physics-based arcade games, the most notable one was Ball Revamped 2.
* Cactus McCoy: platformer series starring a humanoid plant who uses a wide variety of weapons to fight bandits in the Wild West.
* The Classroom: minimalistic stealth series where your goal is to cheat in an exam.
* Crystal Story & Crystal Story II: long JRPG with a touch of comedy.
* Cursed Treasure: fantasy-inspired tower defense.
* Exit Path: platformer starring a sticky figure running away from a totalitaristic regime. It also had a multiplayer mode, something very unusual for this type of games, which I assume unfortunately won't be playable with this as it used ArmorGames' servers.
* Fancy Pants Adventures: platformer series with hand-drawn-style graphics, fast pace and very fluid movements.
* Get Home: experimental 5-minute platformer built around a song.
* IndestructoTank: a game about a jumping tank that was perfect between study sessions in exam season.
* Infectonator: epidemic simulator.
* Kingdom Rush: arguably the most popular tower defense franchise.
These free Flash games are what nowadays are sold as "indie games", only back then developers (often one-man teams) used to upload them for free to show off what they could do.
