Quite a lot yes.
However and since I am far from an expert in tabletop games, I still find some games that have extensive rules actually making sense and pushing in the direction of realism and immersion, rules that have an actual meaning and that are not just here for the sake of being obnoxious to the players, can be very interesting.
Then it is always to the GM to keep what is good and triage everything to make it more enjoyable and keep his players immersed instead of spending time with shitloads of dices and math.
Oh, definitely. Rules-heavy games can be just as fun as rules-light ones, as long as those rules support the general feel you're aiming for, and don't get in the way of immersion.
Table-top RPGs have been my primary hobby for the past twenty years. I've played a
contraptionton of different games, and enjoyed most of them. Sometimes I'm in the mood for a dungeon crawl, in which case I can have a blast playing some shape and form of D&D (including Pathfinder, which I agree with Graelyn is an excellent stepping-stone up from 3.5). Sometimes I'm in the mood for dark modern fantasy drama, in which case the various WoD games are excellent places to turn. GURPS, Ars Magica, 7th Sea, Blue Planet, Deadlands, WHFRP (earlier editions, oh, and the new WH40K RPGs too), Rolemaster (incl. MERP), Earthdawn, FADE (playing in a forum game using that system right now, actually), Shadowrun, Cyberpunk 2020 (which needed better armor rules and a completely different cyber-tolerance system, but hey), Call of Ctulhu (as long as the focus is on RP and not on puzzles, which I thoroughly detest in RPGs), Mutant Chronicles, and several other games and systems too obscure to name. I've played all of them, I've enjoyed most of them, and they all have a different
feel, created by the setting, the rules and most importantly the kind of characters and drama that thrive within them. Incidentally, I'm of the opinion that the best game to ever come out of the TSR/WotC camp (and I've enjoyed D&D in its various incarnations and settings from Basic up to 3.5 and on to Pathfinder, which is still D&D in all but name) was Alternity.
And sometimes - quite often, in fact, I play EVE, after all - I'm in the mood to play something that has the
feel of a computer RPG to it. But in those cases, I just play a computer game.
