Hello VGC! This is my first post here.
As you've reviewed World Cup Soccer,I'd recommend you to review its Famicom version named "Kunio Kun No Nekketsu Soccer League" (Technos Soccer League,in English).This game is wayy better than NES World Cup Soccer.It's fluid,has better soundtrack,has great 2-player gameplay and has better interface than World Cup Soccer.
Though,I'd like to say that i've never played it originally on NES or Famicom,as both the systems were never officially released in my country (India) back then,instead of that i've played the same game on those Chinese made Famiclones,on a "Polystation" to be precise.
The only drawback of the "Kunio Kun No Nekketsu Soccer League" is that being a Famicom game it's available in Japanese Only,though several attempts have made to translate it in English and other languages,so you can easily find various translated versions of the game online on those ROM sites.
Here's English one that i've found:
