The Tower SP
2005 video game

The Tower SP (ザタワーSP) is a 2005 construction and management simulation video game developed by Vivarium and published by Nintendo for the Game Boy Advance. It was released in March 2005 in Japan and April the same year by Sega in North America. It is a port and revision of SimTower (1994), which Vivarium's predecessor OPeNBook developed, with some elements of its sequel Yoot Tower (1998). In the game, the player is tasked to construct a tower for their company boss, Yama.
Gameplay
Differences from SimTower
In The Tower SP, perhaps due to the limitations of the Game Boy Advance's system, the "Tower" status (the highest available tower rating) is obtained with a population of 2,000 people; a goal which is quite hard considering the height limit for the building is 50 floors(35 floors for the commercial tower) and a certain foundation width. The width is slowly expanded as Yama gets deregulation for the roads and buildings surrounding the player's Tower. However, reaching that population is not enough. The "Tower" status is only awarded when a wedding takes place in the building, which only occurs when a cathedral is constructed at the maximum height, the cathedral can be reached without any stress, the cathedral is full, and when there are 2,000 people in the building at that moment.
Achieving a "Tower" status with the Office Building unlocks the possibility of building a "Commercial Building". The site permits construction of a higher lobby at the ground floor, but doesn't permit the construction of building offices, condominiums, medical centers, security offices, nor recycling centers, allows up to 3 cinemas in the building (whereas the Office Building only allowed one), as well as a spa with water from a hot spring and hotel suites (once the appropriate star rating is reached).

Why this record matters
The phrase “2005 video game” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 24, 2026. The linked authority identifier is Q7769738. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2005, 1994 and 1998.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
