The FF Tactics example above is just the same short sound being triggered a lot, possibly analogous to each character, possibly at a predetermined rate that starts and stops with the text scroll.
It doesn't sound overtly synthesised, so it could have been created either way, but other than being short and mid-heavy its defining characteristic is its 'roundness' - it's not a 'click' (which would be unpleasant to hear repeatedly), it's got a bit more shape to its attack which softens it a little. You can create that kind of thing with a little bit of a fade in on any short sound, but if you started with something that's in the right ballpark (I dunno, tapping your knuckle on wood?) and then shape it a bit from there then you'll be headed in the right direction.
There's a really handy free VST plugin called Transpire which makes tweaking the transients of a sound a breeze - it's essentially a super-intuitive compressor. I use it to tame 'clicky' stuff all the time - could be useful with this kind of task:
