Uff, plenty of options I'd say
Trying to have them in categories in no special order with few personal experiences
(but frankly they overlap very often):
*New Game+
-Infinity Blade 1,2,3 - mobile
The vgame carries the experience level & items
You go all the way up to the God king, defeat him and start over (bloodline cycle)
The end? When you decide when you are bored enough of leveling up...
Great ios vgames, a shame they were removed when Apple decided 32bits to die
-Valfaris
It has the Full Metal Mode, quoted:
"essentially a New Game+ that turns the deadly up to MAX by remixing various aspects of gameplay.
The new mode will unlock after completing the game, so if you've already got a 'Clear Game' save file,
you'll be able to jump into Full Metal Mode as soon as the update's been installed.
Here's a rundown of features:
-All weapons, upgrades, and upgrade items carry over between runs
-Enemies have increased health, attack, and aggression
-Bosses receive the same buffs - with additional attack patterns
-Therion takes more damage
-New Destroyer Class Weapon
-New Achievement for defeating Full Metal Mode"
Heard also nice, but pending to me:
-Dishonored 2
-Batman: Arkham Knight
*Huge number of combinations
-Battleheart Legacy. quoted:
"• An astounding 150+ unique skills across 12 classes to customize your character with.
Poison your foes, crush them with giant two-handed weapons, put them to sleep with a song,
or simply blow them up with a meteor strike. And with our unique multi-classing system,
it's possible to combine classes into a nearly limitless number of combinations.
• Over 200 unique pieces of equipment to further tailor your character's play style"
*Special endings / Fighting vgames
-Street Fighter 2. Beat the story without losing a single round. Did I mention it has 8 characters to master?
-Mortal Kombat Trilogy. +20 characters, special moves, fatalities, brutalities, animalities, friendships...
*Survival Mode
-Plants vs Zombies. (Don't clearly remember) Unlocked once you finish the story mode
Also has a Zen Garden to waste as much time as wanted
*Collectibles / 100% completion
-GTA3, GTAVC. After/While finishing the story, lots of time needed to finish:
side missions (phone, vehicles, rampages, gangs), find the packages, perform the unique jumps...
Big part of mastering those vgames happens there
*Sports / versus: FIFA, NBA, NFL (career, tournament, versus. Many teams/roasters to choose)
*MMOs:
-World of Warcraft: The story mode alone falls short to all it can offer
*Re-visit long time ago played vgames
