Good spread dude. I forgot about a couple of those and while my ipad2 is long dead I did get a 5s last year so I did recover some fine goodies I once owned.
My phone has --
A Dark Room
Arkanoid
Blazing Star
Dragon Fantasy
DOOM
Final Fantasy 1
(1942) First Strike
Flight Control
Gunman Clive
Hypership Out of COntrol
Infinity Blade (have 2 just not on it)
Mega Man II
Metal Slug
Metal Slug 3
Monument Valley (was free for a day a few weeks back)
Mr Driller
North vs South
Out There Omega Ed
Powerpros Baseball
Questlord
Shantae (meh)
Sky Force(great shooter, hard too)
Solitaire (free one)
Terraria
Time Crisis
VectorRacing
Vega Conflict (also on pc, facebook, and android)
Woah Dave
Wolfenstein 3D
Zookeeper
And then there's Pinball Arcade and ZaccariaME (it's free, many good real pinball tables from an Italian maker in the 70s-80s but has many more to unlock.)
I know I had more on the iPad, but some stuff wasn't universal and is a goner. I never paid more than a few dollars on most of it, the most probably was $7 for 1/2 off on FF1 and discounted table packs at 1/2 off for Pinball Arcade as I know I have season1 and 2 on it. Quite a few of them were freebies of the day or .99 cent deals I found through
www.iosnoops.com. I do the same shenanigans with Android now using the app called App Sales (or their website) which does the same with freebies and cheap cuts and with google surveys I get a lot for free stacking credit.
