Understanding hiragana-only texts in videogames


I've been reading since a long time ago that reading hiragana only texts is
quite difficult or frustrating because you don't know where a word begins or
ends, I understand that and the importance of kanji to read more easily.

So I was wondering, how do Japanese people play hiragana only games like
pokémon or those of the famicom (NES) that use only kana. I know this games
are oriented to children because they don't know kanji, but how do the adults
understand these games?

On average, do Japanese speakers find it more difficult to read texts without
kanji? Are there any methods to improve the legibility of hiragana-only texts?




In the famicom/NES era, kanji was not available, and many games used some
spaces between phrases. Spaces are usually inserted before nouns and verbs,
but not before particles.

With the aid of spaces Japanese adults can understand kana-only sentences
easily, just like in English. Actually native speakers can even read this

very fluently.

Another common strategy is to [use katakana a bit more than
usual](https://japanese.stackexchange.com/q/23093/5010).
