I am not really a fan of rpg tracks because i am not able to master all the balance parts on pipes and circuit borders (This is maybe due to the fact that I use the keyboard instead of a controller?)...
I hear you :-> would be the same for me, i got the feeling it is easier for me with pad^ ^
Probably Kryw (who drives with keyboard does not have many pipe-balancing parts and long ledges in his early RPG tracks because he is a keyboard-driver^ ^
...on the other hand, as you can read here in the forum, some insanely gifted 'RPG driving gods', manage to do it with keyboard (athough it is a mystery for me how they manage to do it :- >)
but tecfan and realized can do it^ ^ and not mentioned here in the forum yet, Klody (often on RPG Unlimited), is also a gifted Keyboard-driver...
TimeBreaker, who unquestionably is very fast since a long time^ ^, struggled on a few obstacles with his keyboard (i especially remember him cursing when failing epically in Poseidon's Wrath^ ^)...but sometimes you can use a different technique, "hook" the weel into the ledge...Tecfan made a Video Tutorial for that...this technique solved TimeBreaker's troubles :->...
...as i stated: i think there are not enough easy RPGs (yet :->) ...but i still wanted to try to answer your initial question :- ) so here are my suggestions, for which i voted:
Sobékite
Sesostris
RPG map 1
Temple of Doom
Palace India
Occam's Tribute
MONTEZUMAS T.
Labyrinth II
Apocalyptic Hybrid
Karnak
and also 'others', but out of competition^ ^, because it is not Stadium Environment:
"A Dragaons' Tale" by sol666, if you own (or can borrow ;- >) an United Account, you might want to try it...
...it probably is the easiest RPG of all so far^ ^ (but thx to the fantastic MT work still blessed with an wonderful atmosphere), but like in most other RPGs you might like to follow a "Tour Guide"^ ^
some drivers like it better to search the route by themselves, but as for me i love nothing more than follow a friendly Tour Guide^ ^ ...i am bad enough as driver^ ^, getting lost in the Dungeons, Temples and Pyramids does not help my motivation :- > i struggle enough to overcome the obstacles :->
