[[http://www.nekogames.jp/g.html?gid=PRM Parameters]] is a Japanese [[RolePlayingGame RPG]] WebGame with no proper graphics, no sound effects, no music and no story. Essentially, it is an RPG stripped down to its basic mechanics-click on boxes to fight enemies and complete missions, while upgrading your stats, unlocking rooms, and such. Your objective is to "kill" all the enemies (yellow squares) and defeat the final boss.

Despite its extreme simplicity, this game is very addictive.

!! '''Tropes Associated with Parameters'''

* AffectionateParody: To [=RPGs=] in general.
* AchievementSystem: Accomplishing certain tasks, such as collecting money non-stop, will unlock certain squares. These squares are one-use but provide sizeable bonuses.
* BettingMiniGame: You get to unlock a slot machine-like game, which can be a good source of money if you know how it works.
* BonusBoss: When you beat the FinalBoss, the box at the bottom becomes this. It has 9999 health and regenerates health very quickly.
* BraggingRightsReward: The one-time square that allows you to double your attack power is unlocked... after you beat the FinalBoss. It's pretty much only useful for the only enemy left (which is the BonusBoss), and that's about it.
* ClimaxBoss: The bottom-most box, being the biggest one of them all and sporting more HP than all other boxes, can easily lead the player to assume that it's the most threatening enemy on the board and the last one they have to subdue. [[spoiler:It's not. The final boss is an unassuming square that only becomes accessible once all other enemies are defeated, and to make up for its small size it has several health bars.]]
* DamageIncreasingDebuff: Both the FinalBoss and the BonusBoss can temporarily lower your defence when they attack you.
* DeathIsASlapOnTheWrist: Losing all your health just means that you have to regenerate it back. Your attack and defense also drop to zero and have to regenerate too, so you can't just top off your health and jump straight back into the fray.
* DeconstructionGame: This game is pretty much an RPG in its bare-bones form. Unlike ''VideoGame/ProgressQuest'', it requires player interaction.
* DumpStat: Defence. Considering that it is impossible to buy RCV upgrades (unless you unlock the ability to buy skill points), the Attack upgrades are too expensive compared to buying skill points to level up attack, and Defence upgrades are far cheaper, you're best off buying all the Defence upgrades rather than spending skill points in it.
* {{Engrish}}: Collect enough money to fill up the combo bar and you get the message "MAXIMAM COMBO"
* ExactlyWhatItSaysOnTheTin: This game is about RPG parameters, and almost nothing else.
* GlassCannon: You start out like this at first. Buy some defence ups if you want to survive your first enemy.
** Some of the enemy rectangles have deceptively low health, but their defense is good and their attack is ''painful''.
* GottaCatchEmAll: The letters, which RandomlyDrops while you complete missions or defeat enemies.
* HealthDamageAsymmetry: You have about 100 health or so, and cannot increase it through normal means. The enemies at the beginning only have 30-40 hit points, but later on they will start getting above 300. Fortunately, your attack damage is most probably going to be higher than theirs if you've been level grinding a lot.
* LevelUpFillUp
* PointBuildSystem
* RegeneratingHealth: For both you and the enemies.
* StoneWall: The FinalBoss doesn't do that much damage if your defences are good, but he takes very little damage. And it regenerates health very quickly as its health gets lower.
* TurnsRed: As the "final boss" loses health bars, his health regeneration gets ''a lot'' faster.
* UnwinnableByMistake[=/=]UnwinnableByInsanity: Both averted. If you run out of keys to unlock enemies or quests, you can grind $400 on a completed quest and use it to buy a key (pretty much needed if you want to unlock everything). Similarly, if you failed to collect any exp before it disappeared (and thus lost out on {{Skill Point}}s needed to defeat the enemies), there's a special square where you can buy 1 skill point for $200.
