To be fair, companies kind of HAVE to say this in order to protect their end of ensuring sales.
They can't say 'Actually no, please buy XSEED's Cold Steel 1-2 releases, or XSEED's Trails in the Sky releases first' and risk people determining they either don't like the series (loss of sales) or taking their time with previous installments (loss of opening week sales).
They couldn't even suggest playing their own Crossbell games first either because, despite taking two perfectly acceptable scripts from GeofrontTeam (who also translated the extra EVO content for them), they just went ahead and changed most of the script anyway.
